You're using the very same form as the doc. "This form" in the doc refers to "repo refspec", i.e. something like "a b:c", which is what you use. The "refs/heads/" part is just there to disambiguate between possible different matches on the remote side (refs/heads/foo, refs/tags/foo, refs/remotes/bar/foo, ...).
