[PATCH v3 0/9] docs: interpret-trailers: reword and add examples

This series makes some small improvements to the docs for git-interpret-trailers. The intent is to make it easier to read for beginners who have never used this command before.

Changes from v2 to v3 =====================

 * Rebased on top of "master" at fe86abd751 (Git 2.41, 2023-06-01). The only
   conflict was in Patch v2 4/9
   (https://lore.kernel.org/git/783a0b1e00309e9bcf13494908d99317df72f0d6.1683839975.git.gitgitgadget@gmail.com/),
   because cbb83daeaf (doc: interpret-trailers: fix example, 2023-05-01)
   added the "subject/message" style for the examples that did not have any
   message text in them. These examples' additional message lines have been
   replaced with Lorem ipsum... like the others in Patch v2 4/9.

Changes from v1 to v2 =====================

In order of significance:

 * The phrase "commit message part" has been removed.
 * The word "message" is always used as part of the bigger phrase "commit
   message".
 * Deprecation language for trailer.<token>.command has been updated to
   minimize whitespace churn, while also tweaking the 2nd paragraph to
   reduce duplication.
 * The phrase "Lorem ipsum..." is always only used to stand in for the body
   paragraph(s) of a commit message.
 * Grammar fixes have been squashed together (01+06 previously).

Linus Arver (9):

  doc: trailer: use angle brackets for <token> and <value>
  doc: trailer.<token>.command: emphasize deprecation
  doc: trailer: mention 'key' in DESCRIPTION
