I want to check that the file actually begins with "gitdir: " and then
extract the path, so I'm not sure if using string functions is that
simple/fast.

Limiting the recursion is very simple, but I'm not sure people are
supposed to stumble on that. More importantly this probably calls for a
different error message, thus a new error result that I am not ready to
implement. But it could be another patch.
But I suppose I can add a simple "return 0" limit to the recursion if
needed, let me know.
