Support '*' in the middle of a refspec

Browse Source 
In order to keep the requirements strict, each * has to be a full path
component, and there may only be one * per side. This requirement is
enforced entirely by check_ref_format(); the matching implementation
will substitute the whatever matches the * in the lhs for the * in the
rhs.
