[PATCHv5 0/2] clone: respect additional configured fetch refspecs during initial fetch

["SZEDER Gábor" <szeder.dev@gmail.com>]

Only small, straightforward adjustments, mostly based on Jonathan's
comments.

The one exception is passing the default refspec using
strbuf_detach(), because add_fetch_refspec() doesn't make a copy of it
internally.  It doesn't make any difference in practice, because
strbuf default_refspec remains unaltered til the very end, but this is
the right thing to do.
