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.

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

For sorting purposes, fields with numeric values sort in numeric order
(`objectsize`, `authordate`, `committerdate`, `creatordate`, `taggerdate`).
