"git rebase -i" sometimes left intermediate "# This is a
combination of N commits" message meant for the human consumption
inside an editor in the final result in certain corner cases, which
has been fixed.
* js/rebase-i-clean-msg-after-fixup-continue:
rebase --skip: clean up commit message after a failed fixup/squash
sequencer: always commit without editing when asked for
rebase -i: Handle "combination of <n> commits" with GETTEXT_POISON
rebase -i: demonstrate bugs with fixup!/squash! commit messages

During a series of fixup/squash commands, the interactive rebase builds
up a commit message with comments. This will be presented to the user in
the editor if at least one of those commands was a `squash`.
In any case, the commit message will be cleaned up eventually, removing
all those intermediate comments, in the final step of such a
fixup/squash chain.
However, if the last fixup/squash command in such a chain fails with
merge conflicts, and if the user then decides to skip it (or resolve it
to a clean worktree and then continue the rebase), the current code
fails to clean up the commit message.
This commit fixes that behavior.
The fix is quite a bit more involved than meets the eye because it is
not only about the question whether we are `git rebase --skip`ing a
fixup or squash. It is also about removing the skipped fixup/squash's
commit message from the accumulated commit message. And it is also about
the question whether we should let the user edit the final commit
message or not ("Was there a squash in the chain *that was not
skipped*?").
For example, in this case we will want to fix the commit message, but
not open it in an editor:
pick <- succeeds
fixup <- succeeds
squash <- fails, will be skipped
This is where the newly-introduced `current-fixups` file comes in real
handy. A quick look and we can determine whether there was a non-skipped
squash. We only need to make sure to keep it up to date with respect to
skipped fixup/squash commands. As a bonus, we can even avoid committing
unnecessarily, e.g. when there was only one fixup, and it failed, and
was skipped.
To fix only the bug where the final commit message was not cleaned up
properly, but without fixing the rest, would have been more complicated
than fixing it all in one go, hence this commit lumps together more than
a single concern.
For the same reason, this commit also adds a bit more to the existing
test case for the regression we just fixed.
The diff is best viewed with --color-moved.

When multiple fixup/squash commands are processed and the last one
causes merge conflicts and is skipped, we leave the "This is a
combination of ..." comments in the commit message.
Noticed by Eric Sunshine.
This regression test also demonstrates that we rely on the localized
version of
# This is a combination of <number> commits
to contain the <number> in ASCII, which breaks under GETTEXT_POISON.

It has been reported that strategy arguments are not passed to `git
merge` correctly when rebasing interactively, preserving merges.
The reason is that the strategy arguments are already quoted, and then
quoted again.
This fixes https://github.com/git-for-windows/git/issues/1321

Interactive rebase was ignoring '--rerere-autoupdate'. Fix this by
reading it appropriate file when restoring the sequencer state for an
interactive rebase and passing '--rerere-autoupdate' to merge and
cherry-pick when rebasing with '--preserve-merges'.

Rebase accepts '--rerere-autoupdate' as an option but only honors it
if '-m' is also given. Fix it for a non-interactive rebase by passing
on the option to 'git am' and 'git cherry-pick'. Rework the tests so
that they can be used for each rebase flavor and extend them.

Since 8389b52 (git-rerere: reuse recorded resolve., 2006-01-28), git-am
will call git-rerere to re-use recorded merge conflict resolutions if
any occur in a threeway merge.
Add a test to ensure that git-rerere is called by git-am (which handles
the non-interactive rebase).

Breaks in a test assertion's && chain can potentially hide failures from
earlier commands in the chain by adding " &&" at the end of line to the
commands that need them.

If '--[no-]allow_rerere_autoupdate' is passed when 'git rebase -m' is
called and a merge conflict occurs, the flag will be forgotten for the
rest of the rebase process. Make rebase remember it by saving the
value.

When a rebase is resumed, interactive rebase remembers any merge
strategy passed when the rebase was initated. Make non-interactive
rebase remember any merge strategy as well. Also make non-interactive
rebase remember any merge strategy options.
To be able to resume a rebase that was initiated with an older version
of git (older than this commit), make sure not to expect the saved
option files to exist.
Test case idea taken from Junio's 71fc224 (t3402: test "rebase
-s<strategy> -X<opt>", 2010-11-11).

The sub commands '--continue', '--skip' or '--abort' may only be used
standalone according to the documentation. Other options following the
sub command are currently not accepted, but options preceeding them
are. For example, 'git rebase --continue -v' is not accepted, while
'git rebase -v --continue' is. Tighten up the check and allow no other
options when one of these sub commands are used.
Only check that it is standalone for non-interactive rebase for
now. Once the command line processing for interactive rebase has been
replaced by the command line processing in git-rebase.sh, this check
will also apply to interactive rebase.

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.
