I agree that we are safe when it is absolute (no room for prefix to
take part); my question was more about repo_git_path() that derives
its value from repo->gitdir which may or may not be absolute.

Does it always give you absolute, or sometimes it is relative and
sometimes it is absolute?

"git grep -e 'add -e' t/" finds t3702.
