[Message part 1 (text/plain, inline)]

Very odd.
C-d runs the command gnus-summary-enter-digest-group

When used on the attached article, it wipes out two http links,
turning them into a message break:

 .  1 200627||Rob Slade     :Risks for charities, non-profits, small groups
 .  1 700101||nobody        :(none)
 .  1 200626||Gabe Goldberg :AI Ethics: IP Protection for AI-generated and AI-assisted works

Subject: notsp: triggered by a dot

It turns out https://debbugs.gnu.org/cgi/bugreport.cgi?bug=42075 was
triggered by a dot in a separator bar:
--------------------------------------.--------------------------------
there in that Risks Digest Volume 32 : Issue 04.
Odd that a dot could trigger such problems deep later in the document.

It also triggers the smaller separator bars to appear after each article
after pressing ^D.

Good thing the dot only appeared in that issue of Risks Digest.

The digest parser is just guessing what the separators are, and it will
guess wrongly when the format is unregular, as it is here.  So I don't
think there's anything to fix here, and I'm closing this bug report.
