Is there any rollback_lock_file() or commit_lock_file() call on the
shallow lock file in the files involved in this patch that does not
need a call to reset_repository_shallow() left after your work?

What I am trying to get at is if it would be safer to have a pair of
thin wrapper for rolling back or committing a new version of new
shallow file, e.g. rollback_shallow_file() + commit_shallow_file(),
and replace calls to {rollback,commit}_lock_file() with calls to
them.
