When fast-forwarding we do not create a new commit so .git/MERGE_MSG
is not removed and can end up seeding the message of a commit made
after the rebase has finished. Avoid writing .git/MERGE_MSG when we
are fast-forwarding by writing the file after the fast-forward
checks. Note that there are no changes to the fast-forward code, it is
simply moved.
Note that the way this change is implemented means we no longer write
the author script when fast-forwarding either. I believe this is safe
for the reasons below but it is a departure from what we do when
fast-forwarding a non-merge commit. If we reword the merge then 'git
commit --amend' will keep the authorship of the commit we're rewording
as it ignores GIT_AUTHOR_* unless --reset-author is passed. It will
also export the correct GIT_AUTHOR_* variables to any hooks and we
already test the authorship of the reworded commit. If we are not
rewording then we no longer call spilt_ident() which means we are no
longer checking the commit author header looks sane. However this is
what we already do when fast-forwarding non-merge commits in
skip_unnecessary_picks() so I don't think we're breaking any promises
by not checking the author here.

If the user runs git log while rewording a commit it is confusing if
sometimes we're amending the commit that's being reworded and at other
times we're creating a new commit depending on whether we could
fast-forward or not[1]. For this reason the reword command ensures
that there are no uncommitted changes when rewording. The reword
command also allows the user to edit the todo list while the rebase is
paused. As 'merge -c' also rewords commits make it behave like reword
and add a test.

This removes the ability to inject "poison" gettext() messages via the
GIT_TEST_GETTEXT_POISON special test setup.
I initially added this as a compile-time option in bb946bba761 (i18n:
add GETTEXT_POISON to simulate unfriendly translator, 2011-02-22), and
most recently modified to be toggleable at runtime in
6cdccfce1e0 (i18n: make GETTEXT_POISON a runtime option, 2018-11-08)..
The reason for its removal is that the trade-off of maintaining it
v.s. what it's getting us has long since flipped. When gettext was
integrated in 5e9637c6297 (i18n: add infrastructure for translating
Git with gettext, 2011-11-18) there was understandable concern on the
Git ML that in marking messages for translation en-masse we'd
inadvertently mark plumbing messages. The GETTEXT_POISON facility was
a way to smoke those out via our test suite.
Nowadays however we're done (or almost entirely done) with any marking
of messages for translation. New messages are usually marked by their
authors, who'll know whether it makes sense to translate them or
not. If not any errors in marking the messages are much more likely to
be spotted in review than in the the initial deluge of i18n patches in
the 2011-2012 era.
So let's just remove this. This leaves the test suite in a state where
we still have a lot of test_i18n, C_LOCALE_OUTPUT
etc. uses. Subsequent commits will remove those too.
The change to t/lib-rebase.sh is a selective revert of the relevant
part of f2d17068fd (i18n: rebase-interactive: mark comments of squash
for translation, 2016-06-17), and the comment in
t/t3406-rebase-message.sh is from c7108bf9ed (i18n: rebase: mark
messages for translation, 2012-07-25).

Some tests were calling set_fake_editor to ensure they had a sane no-op
editor set. Now that all the editor setting is done in subshells these
tests can rely on EDITOR=: and so do not need to call set_fake_editor.
Also add a test at the end to detect any future additions messing with
the exported value of $EDITOR.

The format of the todo list is quite a bit different in the
`--rebase-merges` mode; Let's prepare the fake editor to handle those
todo lists properly, too.
The original idea was that we keep the original command unless
overridden, and because the original todo lists only had `pick` lines
anyway, we could be sloppy and "override" the command by the same
command (i.e. use the sed replacement pattern "pick" instead of "&").
This actually would not have worked with `fixup` and `squash` commands,
but it would appear that we never tried to use the fake editor with
`--autosquash`.
However, in the next commit we want to use the fake editor in
conjunction with `--rebase-merges`, so let's use the correct sed
replacement pattern.
Technically, it is not necessary to take care of the `fakesha` thing
(where we reuse the sed replacement pattern to craft a new todo
command), at least for now, as the only user of that thing overrides the
`action` anyway. Nevertheless, for completeness' sake, we do take care
of it.

Make sure that each short command is tested at least once. To
not exacerbate the runtime of the test script, do not add new
tests, but modify existing ones according to these criteria:
- The test does not have a prerequisite.
- The 'git rebase' command is not guarded by test_must_fail.
The pick commands are optional in the FAKE_LINES variable, but
when used, they do end up in the insn sheet. Test them, too.

The 'edit' command can be used to cherry-pick a commit and then
immediately drop out of the interactive rebase, with exit code 0, to let
the user amend the commit, or test it, or look around.
Sometimes this functionality would come in handy *without*
cherry-picking a commit, e.g. to interrupt the interactive rebase even
before cherry-picking a commit, or immediately after an 'exec' or a
'merge'.
This commit introduces that functionality, as the spanking new 'break'
command.

The verbose output of the test 'reword without issues functions as
intended' in 't3423-rebase-reword.sh', added in a9279c6785 (sequencer:
do not squash 'reword' commits when we hit conflicts, 2018-06-19),
contains the following error output:
sed: -e expression #1, char 2: extra characters after command
This error comes from within the 'fake-editor.sh' script created by
'lib-rebase.sh's set_fake_editor() function, and the root cause is the
FAKE_LINES="pick 1 reword 2" variable in the test in question, in
particular the "pick" word. 'fake-editor.sh' assumes 'pick' to be the
default rebase command and doesn't support an explicit 'pick' command
in FAKE_LINES. As a result, 'pick' will be used instead of a line
number when assembling the following 'sed' script:
sed -n picks/^pick/pick/p
which triggers the aforementioned error.
Luckily, this didn't affect the test's correctness: the erroring 'sed'
command doesn't write anything to the todo script, and processing the
rest of FAKE_LINES generates the desired todo script, as if that
'pick' command were not there at all.
The minimal fix would be to remove the 'pick' word from FAKE_LINES,
but that would leave us susceptible to similar issues in the future.
Instead, teach the fake-editor script to recognize an explicit 'pick'
command, which is still a fairly trivial change.
In the future we might want to consider reinforcing this fake editor
script with an &&-chain and stricter parsing of the FAKE_LINES
variable (e.g. to error out when encountering unknown rebase commands
or commands and line numbers in the wrong order).

Mark comment messages of squash/fixup file ($squash_msg) for
translation.
Helper functions this_nth_commit_message and skip_nth_commit_message
replace the previous method of making the comment messages (such as
"This is the 2nd commit message:") aided by nth_string helper function.
This step was taken as a workaround to enabled translation of entire
sentences. However, doesn't change any text seen in English by the user,
except for string "The first commit's message is:" which was changed to
match the style of other instances.
The test t3404-rebase-interactive.sh resorts to set_fake_editor which
didn't account for GETTEXT_POISON. Fix it by assuming success when we
find dummy gettext poison output where was supposed to find the first
comment line "This is a combination of $count commits.".
For that same message, use plural aware eval_ngettext instead of
eval_gettext, since other languages have more complex plural forms.

Check before the start of the rebasing if the commands exists, and for
the commands expecting a SHA-1, check if the SHA-1 is present and
corresponds to a commit. In case of error, print the error, stop git
rebase and prompt the user to fix with 'git rebase --edit-todo' or to
abort.
This allows to avoid doing half of a rebase before finding an error
and giving back what's left of the todo list to the user and prompt
him to fix when it might be too late for him to do so (he might have
to abort and restart the rebase).

Instead of removing a line to remove the commit, you can use the
command "drop" (just like "pick" or "edit"). It has the same effect as
deleting the line (removing the commit) except that you keep a visual
trace of your actions, allowing a better control and reducing the
possibility of removing a commit by mistake.

A #! line in these files is misleading, since these scriptlets are
meant to be sourced with '.' (using whatever shell sources them)
instead of run directly using the interpreter named on the #! line.
Removing the #! line shouldn't hurt syntax highlighting since
these files have filenames ending with '.sh'. For documentation,
add a brief description of how the files are meant to be used in
place of the shebang line.

In rebase -i --autosquash, ignore all "fixup! " or "squash! " after the
first. This supports the case when a git commit --fixup/--squash referred
to an earlier fixup/squash instead of the original commit (whether
intentionally, as when the user expressly meant to note that the commit
fixes an earlier fixup; or inadvertently, as when the user meant to refer to
the original commit with :/msg; or out of laziness, as when the user could
remember how to refer to the fixup but not the original).
In the todo list, the full commit message is preserved, in case it provides
useful cues to the user. A test helper set_cat_todo_editor is introduced to
check this.

The typical usage pattern would be to run a test (or simply a compilation
command) at given points in history.
The shell command is ran (from the worktree root), and the rebase is
stopped when the command fails, to give the user an opportunity to fix
the problem before continuing with "git rebase --continue".
This needs a little rework of skip_unnecessary_picks, which wasn't robust
enough to deal with lines like
exec >"file name with many spaces"
in the todolist. The new version extracts command, sha1 and rest from
each line, but outputs the line itself verbatim to avoid changing the
whitespace layout.
