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.
