Subject: [PATCH v2 0/1] check_refname_component: Optimize
Message-ID: <1401311055-480-1-git-send-email-dturner@twitter.com>

I just tested the previous patch on a Mac with clang and it needed
some tweaks.

Also, I should clarify that this represents a real use-case: we really
do have tens of thousands of branches on some repos.  It would be nice
if people would clean up after themselves, but they don't.

(Also, it's probably worth adding a shortcut for HEAD at some point,
since that is the most-commonly-used ref, but that's for a later
patch)
