Refspecs for branches in a remote repository start with 'refs/heads/',
so completing those refspecs with 'git config remote.origin.fetch
<TAB>' always offers 'refs/heads/' first, because that's the unique
part of the possible refspecs.  But it does so only after querying the
remote with 'git ls-remote', which can take a while when the request
goes through some slower network to a remote server.

Don't waste the user's time and offer 'refs/heads/' right away for
'git config remote.origin.fetch <TAB>'.

The reason for putting 'refs/heads/' directly into COMPREPLY instead
of using __gitcomp() is to avoid __gitcomp() adding a trailing space.
