[PATCH v2 0/3] doc: interpret-trailers: don't use deprecated config

Replace deprecated `command` with `cmd` (patch 2). While visiting this file also rewrite heredoc examples to use files which are shown with cat(1) (patch 1) and fix two examples that didn’t work properly (patch 3).

§ Changes in v2

First of all I had to send a second version since I messed up sending my v1 cover letter (unencoded Unicode in the subject). But I ended up doing quite a few changes:

1. Patch 1: Junio had some alternative suggestions. Remove trailing
   spaces by using files which are shown with cat(1) and thereby make it
   easier to copy-paste from the docs.
2. Patch 2: Fix discrepancy (see/sign) in commit message (thanks to
   Andrei Rybak)
3. Patch 2: minor commit message correction
4. Patch 3: Fix another example and build on top of it by using the
   typical “subject/message” format instead of an empty file and an
   s-o-b file (a file with just an s-o-b trailer)
