Git Browse Failed to Handle Brand New Repo

[equt]

Git browse would first check the current HEAD and output a git fatal for the following line.

git-extras/bin/git-browse

Line 5 in ad8c77b

branch=$(git rev-parse --abbrev-ref HEAD)

fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'

To reproduce, just run git browse inside a brand new git repo. Casting the error into /dev/null should fix it.
