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`.
However, if the last of these fixup/squash commands 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 diff is best viewed with --color-moved.
