When testing a reworded root commit, ensure that the squash-onto commit
which is created and amended is still the root commit.

The code path that triggered that "BUG" really does not want to run
without an explicit commit message. In the case where we want to amend a
commit message, we have an *implicit* commit message, though: the one of
the commit to amend. Therefore, this code path should not even be
entered.

In this developer's earlier attempt to accelerate interactive rebases by
converting large parts from Unix shell script into portable, performant
C, the --root handling was specifically excluded (to simplify the task a
little bit; it still took over a year to get that reduced set of patches
into Git proper).
This patch ties up that loose end: now only --preserve-merges uses the
slow Unix shell script implementation to perform the interactive rebase.
As the rebase--helper reports progress to stderr (unlike the scripted
interactive rebase, which reports it to stdout, of all places), we have
to adjust a couple of tests that did not expect that for `git rebase -i
--root`.
This patch fixes -- at long last! -- the really old bug reported in
6a6bc5bdc4d (add tests for rebasing root, 2013-06-06) that rebasing with
--root *always* rewrote the root commit, even if there were no changes.
The bug still persists in --preserve-merges mode, of course, but that
mode will be deprecated as soon as the new --rebase-merges mode
stabilizes, anyway.

When running `git rebase --rebase-merges` non-interactively with an
ancestor of HEAD as <upstream> (or leaving the todo list unmodified),
we would ideally recreate the exact same commits as before the rebase.
However, if there are commits in the commit range <upstream>.. that do not
have <upstream> as direct ancestor (i.e. if `git log <upstream>..` would
show commits that are omitted by `git log --ancestry-path <upstream>..`),
this is currently not the case: we would turn them into commits that have
<upstream> as direct ancestor.
Let's illustrate that with a diagram:
C
/ \
A - B - E - F
\ /
D
Currently, after running `git rebase -i --rebase-merges B`, the new branch
structure would be (pay particular attention to the commit `D`):
--- C' --
/ \
A - B ------ E' - F'
\ /
D'
This is not really preserving the branch topology from before! The
reason is that the commit `D` does not have `B` as ancestor, and
therefore it gets rebased onto `B`.
This is unintuitive behavior. Even worse, when recreating branch
structure, most use cases would appear to want cousins *not* to be
rebased onto the new base commit. For example, Git for Windows (the
heaviest user of the Git garden shears, which served as the blueprint
for --rebase-merges) frequently merges branches from `next` early, and
these branches certainly do *not* want to be rebased. In the example
above, the desired outcome would look like this:
--- C' --
/ \
A - B ------ E' - F'
\ /
-- D' --
Let's introduce the term "cousins" for such commits ("D" in the
example), and let's not rebase them by default. For hypothetical
use cases where cousins *do* need to be rebased, `git rebase
--rebase=merges=rebase-cousins` needs to be used.

The `git merge` command does not allow merging commits that are already
reachable from HEAD: `git merge HEAD^`, for example, will report that we
are already up to date and not change a thing.
In an interactive rebase, such a merge could occur previously, e.g. when
competing (or slightly modified) versions of a patch series were applied
upstream, and the user had to `git rebase --skip` all of the local
commits, and the topic branch becomes "empty" as a consequence.
Let's teach the todo command `merge` to behave the same as `git merge`.
Seeing as it requires some low-level trickery to create such merges with
Git's commands in the first place, we do not even have to bother to
introduce an option to force `merge` to create such merge commits.

In the previous patches, we implemented the basic functionality of the
`git rebase -i --rebase-merges` command, in particular the `merge`
command to create merge commits in the sequencer.
The interactive rebase is a lot more these days, though, than a simple
cherry-pick in a loop. For example, it calls the post-rewrite hook (if
any) after rebasing with a mapping of the old->new commits.
This patch implements the post-rewrite handling for the `merge` command
we just introduced. The other commands that were added recently (`label`
and `reset`) do not create new commits, therefore post-rewrite hooks do
not need to handle them.

Once upon a time, this here developer thought: wouldn't it be nice if,
say, Git for Windows' patches on top of core Git could be represented as
a thicket of branches, and be rebased on top of core Git in order to
maintain a cherry-pick'able set of patch series?
The original attempt to answer this was: git rebase --preserve-merges.
However, that experiment was never intended as an interactive option,
and it only piggy-backed on git rebase --interactive because that
command's implementation looked already very, very familiar: it was
designed by the same person who designed --preserve-merges: yours truly.
Some time later, some other developer (I am looking at you, Andreas!
;-)) decided that it would be a good idea to allow --preserve-merges to
be combined with --interactive (with caveats!) and the Git maintainer
(well, the interim Git maintainer during Junio's absence, that is)
agreed, and that is when the glamor of the --preserve-merges design
started to fall apart rather quickly and unglamorously.
The reason? In --preserve-merges mode, the parents of a merge commit (or
for that matter, of *any* commit) were not stated explicitly, but were
*implied* by the commit name passed to the `pick` command.
This made it impossible, for example, to reorder commits. Not to mention
to move commits between branches or, deity forbid, to split topic branches
into two.
Alas, these shortcomings also prevented that mode (whose original
purpose was to serve Git for Windows' needs, with the additional hope
that it may be useful to others, too) from serving Git for Windows'
needs.
Five years later, when it became really untenable to have one unwieldy,
big hodge-podge patch series of partly related, partly unrelated patches
in Git for Windows that was rebased onto core Git's tags from time to
time (earning the undeserved wrath of the developer of the ill-fated
git-remote-hg series that first obsoleted Git for Windows' competing
approach, only to be abandoned without maintainer later) was really
untenable, the "Git garden shears" were born [*1*/*2*]: a script,
piggy-backing on top of the interactive rebase, that would first
determine the branch topology of the patches to be rebased, create a
pseudo todo list for further editing, transform the result into a real
todo list (making heavy use of the `exec` command to "implement" the
missing todo list commands) and finally recreate the patch series on
top of the new base commit.
That was in 2013. And it took about three weeks to come up with the
design and implement it as an out-of-tree script. Needless to say, the
implementation needed quite a few years to stabilize, all the while the
design itself proved itself sound.
With this patch, the goodness of the Git garden shears comes to `git
rebase -i` itself. Passing the `--rebase-merges` option will generate
a todo list that can be understood readily, and where it is obvious
how to reorder commits. New branches can be introduced by inserting
`label` commands and calling `merge <label>`. And once this mode will
have become stable and universally accepted, we can deprecate the design
mistake that was `--preserve-merges`.

changes made to 468165c1d8a442994a825f3684528361727cd8c0.
The topic appears to inflict severe regression in renaming merges,

We do not yet know which exact change in the topic was wrong, but in
the meantime, let's play it safe and revert it out of 'master'

In 0b294c0abf0 (make deleting a missing ref more quiet, 2008-07-08), we
added a test to verify that deleting an already-deleted ref does not
show an error.
Our test simply looks for the substring 'error' in the output of the
`git push`, which might look innocuous on the face of it.
Suppose, however, that you are a big fan of whales. Or even better: your
IT administrator has a whale of a time picking cute user names, e.g.
referring to you (due to your like of India Pale Ales) as "one of the
cuter rorquals" (see https://en.wikipedia.org/wiki/Rorqual to learn a
thing or two about rorquals) and hence your home directory becomes
/home/cuterrorqual. If you now run t5404, it fails! Why? Because the
test calls `git push origin :b3` which outputs:
To /home/cuterrorqual/git/t/trash directory.t5404-tracking-branches/.
- [deleted] b3
Note how there is no error displayed in that output? But of course
"error" is a substring of "cuterrorqual". And so that `grep error
output` finds something.
This bug was not, actually, caught having "error" as a substring of the
user name but while working in a worktree called "colorize-push-errors",
whose name was part of that output, too, suggesting that not even
testing for the *word* `error` via `git grep -w error output` would fix
the underlying issue.
This patch chooses instead to look for the prefix "error:" at the
beginning of the line, so that there can be no ambiguity that any catch
was indeed a message generated by Git's `error_builtin()` function.

It's possible to have libcurl installed but not the curl
command-line utility. The latter is not generally needed for
Git's http support, but we use it in t5561 for basic tests
of http-backend's functionality. Let's detect when it's
missing and skip this test.
Note that we can't mark the individual tests with the CURL
prerequisite. They're in a shared t556x_common that uses the
GET and POST functions as a level of indirection, and it's
only our implementations of those functions in t5561 that
requires curl. It's not a problem, though, as literally
every test in the script would depend on the prerequisite
anyway.

Following a rename of worktree "source" to "destination", the "move
worktree" test uses grep to verify that the output of "git worktree list
--porcelain" does not contain "source" (and does contain "destination").
Unfortunately, the grep expression is too loose and can match
unexpectedly. For example, if component of the test trash directory path
matches "source" (e.g. "/home/me/sources/git/t/trash*"), then the test
will be fooled into thinking that "source" still exists. Tighten the
expression to avoid such accidental matches.
While at it, drop an unused variable ("toplevel") from the test and
tighten a similarly too-loose expression in a related test.

- later, we may call setup_work_tree() and chdir to the
root of the working tree
- further calls to the ref code will use the stored git
directory, but relative paths will now point to the
wrong place
The new test in t1501 demonstrates one such instance (the
bug causes us to write the ref update to the nonsense
"relative/relative/.git").
Since setup_work_tree() now uses chdir_notify, we can just
ask it update our relative paths when necessary.

rebase --merge accepts --keep-empty but just ignores it, by using an
implicit interactive rebase the user still gets the rename detection
of a merge based rebase but with with --keep-empty support.
If rebase --keep-empty without --interactive or --merge stops for the
user to resolve merge conflicts then 'git rebase --continue' will
fail. This is because it uses a different code path that does not
create $git_dir/rebase-apply. As rebase --keep-empty was implemented
using cherry-pick it has never supported the am options and now that
interactive rebases support --signoff there is no loss of
functionality by using an implicit interactive rebase.

Allow --signoff to be used with --interactive and --merge. In
interactive mode only commits marked to be picked, edited or reworded
will be signed off.
The main motivation for this patch was to allow one to run 'git rebase
--exec "make check" --signoff' which is useful when preparing a patch
series for publication and is more convenient than doing the signoff
with another --exec command.
This change also allows --root without --onto to work with --signoff
as well (--root with --onto was already supported).
