WIP: Allow to read shallow clones
patch libgit2 to allow traverse incomplete repos.
This should be fixed upstream https://github.com/libgit2/libgit2/pull/5268, but as we only want to see repos cloned externally with --depth
I can see no much harm on this upstream patch
-
Patch need to check .git/shallow
to be sure not finded parents are expected
