So, I decided to keep Dscho's latest CSS-workaround change intact,
and queued a stupid and obvious workaround clearly marked as a
tentative measure on top of it.  I am planning to merge these two
patches down for the release candidates.

Without your incremental update to git-clone.txt, git-clone.html
rendered through asciidoctor will say wrong things, so we'd need
to apply it anyway.  So I cannot put your patch _on_ _hold_ for
the purpose of the upcoming release, if we wanted to ship a set of
source that produces correct version of git-clone.html.

So in the end, we'd need both ;-).

Thanks, both.

Subject: [PATCH] Doc: fix Asciidoctor css workaround

The previous step introduced docinfo.html to be used to tweak the
CSS used by the asciidoctor, that by default renders <code> inside
<pre> as a block element, breaking the SYNOPSIS section of a few
pages that adopted a new convention we use since Git 2.45.

But in this project, HTML files are all generated.  We do not force
any human to write HTML by hand, which is an unusual and cruel
punishment.  "*.html" is in the .gitignore file, and "make clean"
removes them.  Having a tracked .html file makes "make clean" make
the tree dirty by removing the tracked docinfo.html file.

Let's do an obvious, minimum and stupid workaround to generate that
file at runtime instead.  The mark-up is being rethought in a major
way for the next development cycle, so what the CSS workaround we
added in the previous step may have to adjusted, possibly in a large
way, anyway.
