[PATCH] Include a git-push example for creating a remote branch

["Shawn O. Pearce" <spearce@spearce.org>]

Many users get confused when `git push origin master:foo` works
when foo already exists on the remote repository but are confused
when foo doesn't exist as a branch and this form does not create
the branch foo.

This new example highlights the trick of including refs/heads/
in front of the desired branch name to create a branch.
