git-rebase calls out to merge strategies, but did not support merge
strategy options so far. Add this, in the same style used in
git-merge.
Sadly we have to do the full quoting/eval dance here, since
merge-recursive supports the --subtree=<path> option which potentially
contains whitespace.
This patch does not cover git rebase -i, which does not call any merge
strategy directly except in --preserve-merges, and even then only for
merges.

When performing a non-interactive rebase, sometimes
"git rebase --continue" will fail if an unmodified file is
touched in the working directory:
You must edit all merge conflicts and then
mark them as resolved using git add
This is caused by "git diff-files" reporting a difference
between the index and the filesystem:
:100644 100644 d00491...... 000000...... M file
The fix is to run "git update-index --refresh" before
"git diff-files" as is done in git-rebase--interactive.

We currently do not disable diff.renames configuration while rebase
internally runs "format-patch" to feed "am -3".
The end user configuration for "diff" should not affect the result
produced by the higher level command that is related to "diff" only
because internally it is implemented in terms of it.
For that matter, I have a feeling that format-patch should not even look
at diff.renames, but we seem to have been doing this for a long time so
there is no easy way to fix this thinko.
In any case, here is a much straightforward fix for "rebase".

For git-rebase.sh, --no-ff is a synonym for --force-rebase.
For git-rebase--interactive.sh, --no-ff cherry-picks all the commits in
the rebased branch, instead of fast-forwarding over any unchanged commits.
--no-ff offers an alternative way to deal with reverted merges. Instead of
"reverting the revert" you can use "rebase --no-ff" to recreate the branch
with entirely new commits (they're new because at the very least the
committer time is different). This obviates the need to revert the
reversion, as you can re-merge the new topic branch directly. Added an
addendum to revert-a-faulty-merge.txt describing the situation and how to
use --no-ff to handle it.

We have to deal with two separate code paths: a normal rebase, which
actually goes through git-am; and rebase {-m|-s}.
The only small issue with both is that they need to remember the
original sha1 across a possible conflict resolution. rebase -m
already puts this information in $dotest/current, and we just
introduce a similar file for git-am.
Note that in git-am, the hook really only runs when coming from
git-rebase: the code path that sets the $dotest/original-commit file
is guarded by a test for $dotest/rebasing.

The previous patch didn't parse "rebase --onto A...B" correctly when A
isn't an empty string. It also tried to be careful to notice a case in
which there are more than one merge bases, but forgot to give --all option
to merge-base, making the test pointless.

Protect scripted Porcelains from GREP_OPTIONS insanity
mergetool--lib: simplify guess_merge_tool()
Conflicts:
git-instaweb.sh
|

If the user has exported the GREP_OPTIONS environment variable, the output
from "grep" and "egrep" in scripted Porcelains may be different from what
they expect. For example, we may want to count number of matching lines,
by "grep" piped to "wc -l", and GREP_OPTIONS=-C3 will break such use.
The approach taken by this change to address this issue is to protect only
our own use of grep/egrep. Because we do not unset it at the beginning of
our scripts, hook scripts run from the scripted Porcelains are exposed to
the same insanity this environment variable causes when grep/egrep is used
to implement logic (e.g. "grep | wc -l"), and it is entirely up to the
hook scripts to protect themselves.
On the other hand, applypatch-msg hook may want to show offending words in
the proposed commit log message using grep to the end user, and the user
might want to set GREP_OPTIONS=--color to paint the match more visibly.
The approach to protect only our own use without unsetting the environment
variable globally will allow this use case.

This is in spirit similar to "checkout A...B". To re-queue a new set of
patches for a series that the original author prepared to apply on 'next'
on the same base as before, you would do something like this:
$ git checkout next^0
$ git am -s rerolled-series.mbox
$ git rebase --onto next...jh/notes next
The first two commands recreates commits to be rebased as the original
author intended (i.e. applies directly on top of 'next'), and the rebase
command replays that history on top of the same commit the series being
replaced was built on (which is typically much older than the tip of
'next').

Commit 4cfbe06 introduced the use of "git diff" to show
dirty state in a format more familiar to users. However, it
should have used the plumbing "git diff-files" instead.
Not only is it good practice in general to use plumbing in

git-am and git-rebase are talkative scripts. Teach them to be quiet when
told, allowing them to speak only when they fail or experience errors.
The quiet option is maintained when git-am or git-rebase fails to apply
a patch. This means subsequent --resolved, --continue, --skip, --abort
invocations will be quiet if the original invocation was quiet.
Drop a handful of >&2 redirection; the rest of the program sends all the
info messages to stdout, not to stderr.

The behavior of --verbose is unchanged, but uses a different state

Teach git-rebase a new option --root, which instructs it to rebase the
entire history leading up to <branch>. This option must be used with
--onto <newbase>, and causes commits that already exist in <newbase>
to be skipped. (Normal operation skips commits that already exist in
<upstream> instead.)
One possible use-case is with git-svn: suppose you start hacking
(perhaps offline) on a new project, but later notice you want to
commit this work to SVN. You will have to rebase the entire history,
including the root commit, on a (possibly empty) commit coming from
git-svn, to establish a history connection. This previously had to
be done by cherry-picking the root commit manually.

If you have unstaged changes in your working tree and try to
rebase, you will get the cryptic "foo: needs update"
message, but nothing else. If you have staged changes, you
get "your index is not up-to-date".
Let's improve this situation in two ways:
- for unstaged changes, let's also tell them we are
canceling the rebase, and why (in addition to the "needs
update" lines)
- for the staged changes case, let's use language that is a
little more clear to the user: their index contains
uncommitted changes

It is sometimes desirable to disable the safety net of pre-rebase hook
when the user knows what he is doing (for example, when the original

As a result of implementation details, 'git rebase' could
previously only preserve merges in interactive mode. That
limitation was hard for users to understand and awkward to
explain.
This patch works around it by running the interactive rebase
helper git-rebase--interactive with GIT_EDITOR set to ':'
when the user passes "-p" but not "-i" to the rebase command.
The effect is that the interactive rebase helper is used but
the user never sees an editor.
The test-case included in this patch was originally written
by Stephen Habermann <stephen@exigencecorp.com>, but has
been extensively modified since its creation.

This patch makes it show the ordinary usage string.
If .git/rebase-merge or .git/rebase-apply/rebasing exists, git-rebase
will die with a message saying that a rebase is in progress and the user
should try --skip/--abort/--continue.
If .git/rebase-apply/applying exists, git-rebase will die with a message
saying that git-am is in progress, regardless how many arguments are
given.
If no arguments are given and .git/rebase-apply/ exists, but neither a

With git-am, it sounds awkward to have the patches in ".git/rebase/",
but for technical reasons, we have to keep the same directory name
for git-am and git-rebase. ".git/rebase-apply" seems to be a good
