/* NOTE:
fetchgit has one problem: git fetch only works for refs.
This is because fetching arbitrary (maybe dangling) commits may be a security risk
This is because fetching arbitrary (maybe dangling) commits creates garbage collection risks
and checking whether a commit belongs to a ref is expensive. This may
change in the future when some caching is added to git (?)
Usually refs are either tags (refs/tags/*) or branches (refs/heads/*)
