Hello,
got this new error today when trying to install a package with M-x
list-packages.
When I revert this commit:
7e32e8392ab "Fix recent test regressions"
(Stefan Monnier <monnier@iro.umontreal.ca> 2024-03-22)
the problem disappears. This commit causes a destruction of my custom
file when it gets pp-filled, by adding newlines into #N# syntaxes, like
#1# => #1\n#.
Attached is a test file. If you (pp-fill (point-min) (point-max))
you will see this effect happen near the end of that file.
TIA,
Michael.

I pushed a patch to `master` which should fix this problem, but ... this
is nasty. I was thinking "how quickly one forgets how hard it is to
parse backward" (thinking back to the time where I worked on
`comment-backward`), but while testing I came across a similar problem
that occurs because of the (forward) `scan-sexps` behavior, so it's even
worse than that.

Works for me, thanks.

We call this a "wasps' nest" in Germany (of course using German words),
and I make this experience often.
Anyway, if you come along fixing Bug#24542, that would be - it would be
one more wasp less...
Michael.
