Re: [PATCH 0/4] [GSOC][RFC] ref-filter: add %(rest) atom

> In order to let git cat-file --batch reuse ref-filter logic, in this
> version, the atom %(rest) is added to ref-filter.
>
> Change from last version:
>
>  1. Deleted two commit about %(raw:textconv) and %(raw:filters), their
>     construction will be after letting cat-file --batch uses ref-filter
>     logic.
>  2. Exchange the order of the definition of "cmp_fn" and the declaration of
>     "a_size" and "b_size" in cmp_ref_sorting(), to avoid breaking
>     -Wdecl-after-stmt.
>  3. Delete --rest option, "git for-each-ref" family will reject %(rest) by
>     default.
>  4. Add GPG prefix to some %(raw) tests.
