[PATCH] Add -v option to git-branch.sh

[Lars Hjemli <hjemli@gmail.com>]

Teach git-branch to show sha1 and subject for each branch tip. 

This requires branch names to be max 20 chars for the output to be 
properly aligned. Not optimal, but doing an extra pass just to find 
the longest name didn't seem reasonable either.
