Fixed when git > 2.1.0:
$ ./scripts/create-pull-request -r HEAD^ -u contrib -b rbt/git
fatal: Not a valid revision: rbt/git
ERROR: git request-pull reported an error
This is because newer git requires both local and remote branch named as
rbt/git, but usually, we only named the remote branch as rbt/foo, and
foo for local branch.
Add a option '-l' to fix the problem, default is HEAD.
