ref-filter.c: use trailer_opts to format trailers

Browse Source 
Fill trailer_opts with "unfold" and "only" to match the sub-arguments
given to the "%(trailers)" atom. Then, let's use the filled trailer_opts
instance with 'format_trailers_from_commit' in order to format trailers
in the desired manner.

@ -218,7 +218,10 @@ blank line. The optional GPG signature is `contents:signature`. The
first `N` lines of the message is obtained using `contents:lines=N`.
Additionally, the trailers as interpreted by linkgit:git-interpret-trailers[1]
are obtained as `trailers` (or by using the historical alias
`contents:trailers`).
`contents:trailers`). Non-trailer lines from the trailer block can be omitted
with `trailers:only`. Whitespace-continuations can be removed from trailers so
that each trailer appears on a line by itself with its full content with
`trailers:unfold`. Both can be used together as `trailers:unfold,only`.
For sorting purposes, fields with numeric values sort in numeric order
(`objectsize`, `authordate`, `committerdate`, `creatordate`, `taggerdate`).
