[git-buildpackage] debian-branch vs. git-debian-branch

[Daniel Kahn Gillmor]

hi gbp'ers--

i used to use DEFAULT.debian-branch in gbp.conf when the debian
packaging is on a branch not named "master".  But recently that appears
to not work, and i need to use DEFAULT.git-debian-branch instead.

however the default /etc/git-buildpackage/gbp.conf appears to still call
it DEFAULT.debian-branch in its comments.

I'm using git-buildpackage 0.7.1.  should the default config file be
updated?  or the code changed?  or updated documentation written?
