Fixed a bug with branch names omitting path components.

Git allows branches to be named and organized using path components, e.g using
a branch called "refactoring/feature1", which gets stored under
refs/heads/refactoring/feature1. The previous code omitted everything but the
last path component giving the name "feature1" instead of
"refactoring/feature1" for the branch. This changeset fixes that.
