Look in `gitmerge-maybe-resume': It checks if there's an ongoing merge
(by checking for .git/MERGE_HEAD) and also a status file from a previous
gitmerge run. If that is both the case and the user accepts the resume,
it will jump to `gitmerge-resolve-unmerged', which should add all
non-conflicted files and commit the merge.
