[PATCH 5/7] rebase -i: return control to the caller, for housekeeping

[Ramkumar Ramachandra <artagnon@gmail.com>]

On a successful interactive rebase, git-rebase--interactive.sh
currently cleans up and exits on its own.  Instead of doing these
two things ourselves:

    rm -fr "$dotest"
    git gc --auto

let us return control to the caller (git-rebase.sh), to do the
needful.  The advantage of doing this is that the caller can implement
a generic cleanup routine (and possibly other things) independent of
specific rebases.
