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

Hello,

Since a few days ago, Gnus sometimes applies gnus-cite faces to
paragraphs below the actual citations.  For example, save the attached
article somewhere, then, from emacs -Q:

- M-x gnus-no-server
- G f /path/to/repro.mbox
- RET RET

There are a few things that seem to go wrong with fontification of
citations; for example, the line that starts with "That is a concern" is
erroneously fontified with gnus-cite-1.

I've tried to bisect this, and Git points out 2021-02-07 "Use
`line-number-at-pos' in `count-lines'" (7c5938ad7d).

When time permits, I'll start looking into what causes the bug, and
maybe whip up a test case; I figure someone more familiar with the code
might easily beat me to it though, so I'm reporting this before having
fully figured it out.

This was fixed in

a few days ago, I believe.

Indeed it was 🤦

I'll close this then; apologies for the noise!
