Hi, Small patch set for review. Patch 1 cleans up some comments inside the eclass, while patch 2 removes unused 'is_branch' variable. Finally, patch 3 adds support for passing any of the 'refs/*' rather than 'refs/heads/*' only. This was requested by vapier in #556822 [1].
The patches can be also found in 'git-r3_support_any_refs' branch in our Gentoo repository. Best regards, Michał Górny [1]:https://bugs.gentoo.org/show_bug.cgi?id=556822
