bug#42397: [PATCH v2 14/16] * lisp/font-lock.el: No longer use headings as end of section markers.

[Jonas Bernoulli <jonas@bernoul.li>]

Each section ends right before the following section begins and IMO
that means that it is unnecessary to mark the end of sections.

For users of `outline-minor-mode' the old end-of-section markers were
a distraction.  They made it much harder to parse the overview outline
state because each section heading was followed by a end-of-section
marker that was formatted as a section heading.  Because of this I
wanted to remove the end-of-section markers.

But as Eli pointed out these sections are long and not everyone uses
`outline-minor-mode'.

So instead of removing them, I am turning the end-of-section markers
into regular comments (beginning with just two semicolons) instead of
section headings (beginning with tree semicolons).  That way users of
`outline-minor-mode' won't be distracted by them and others can still
benefit from the markers as before.
