[pacman-dev] [PATCH] libmakepkg/source/git: Use --bare with a refspec instead of --mirror

[Johannes Löthberg]

This pulls in all of the branches in the same way as --mirror, but won't
also pull in all of the non-branch references.

For example the refs/pull/*/{head,merge} references that GitHub creates
for every PR that has ever been opened against the repo can pull in a
very large amount of objects that aren't useful, and which can massively
inflate a repository.
