Subject: [PATCH v4 0/3] doc: introducing synopsis para
Message-ID: <pull.1766.v4.git.1725573126.gitgitgadget@gmail.com>
In-Reply-To: <pull.1766.v3.git.1723389612.gitgitgadget@gmail.com>

In the continuation of the simplification of manpage editing, the synopsis
processing that was developed for synopsis paragraph style is also applied
to all inline backquoted texts.

Refining the magic regexp took more time than expected, but this one should
really enhance writers'experience. I had to fight a bit more with
asciidoctor, due to discrepancies between version 2.0 on my laptop and the
1.5.6 used by Github actions.

The git-init and git-clone manpages are converted to this new system.

Changes since V1:

 * switch to sed for asciidoc filter and refine the regex for support under
   macOS

Changes since V2:

 * introduce the s macro to freely apply synopsis styling wherever needed,
   without formatting hassle.

Changes since V3:

 * replace s macro by direct processing of literal text at the level of
   output processors.
