I don't think that it makes a big deal either way, but I wonder about
moving 'repo_is_descendant_of' to the header file, and making
'is_descendant_of' be 'static inline int' as you defined it here.
Since this has already graduated up to master already, I don't think
that it's worth going back just to shuffle this code around, but I was
wondering if you had any specific reason for doing it this way.
