Subject: [PATCH v4 0/9] docs: interpret-trailers: reword and add examples

From: "Linus Arver via GitGitGadget" <[email-masked]>

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.

Updates in v4
=============

 * vs Patch v3 3/9: Reworded a sentence to avoid ambiguity with the word
   "ignored".
 * vs Patch v3 4/9: Replaced "Lorem ipsum..." in favor of "body text" which
   is shorter and more obvious (and search-friendly).
 * vs Patch v3 8/9: Expanded the explanation about 'trailer..key' and its
   convenience, instead of only stating how to use this option.

Updates in 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/783a[email-masked]/),
   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.

Updates in 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).
