Re: [PATCH 2/3] show_ref(): remove unused "flag" and "cb_data" arguments

I suppose, though I didn't verify, that the old function signature was
a vestige of its earlier having been used as a callback function.  But
it doesn't really matter; the point is that the extra arguments are
currently not needed.

Yeah, since 8a65ff7 (Generalize the "show each ref" code in receice-pack,
2005-07-02) the function has always been fed to for_each_ref(), but when
6b01ecf (ref namespaces: Support remote repositories via upload-pack and
receive-pack, 2011-07-08) introduced show_ref_cb() as the callback that
uses show_ref() as a helper, it forgot to do the clean-up in this patch.
