bug#29767: 26.0.90; Failing auto-fill in message-mode because of bad state (comment-skip-end)

["Jose A. Ortega Ruiz" <jao@gnu.org>]

I think i've found a reliable way to reproduce the problem.

If i write my in-line response by opening a line in the middle of the
citacion text with a plain RET or C-o, things work as expected.

But, i i go to the middle of cited text and press M-j (i.e.,
indent-new-comment-line, which is an alias for comment-indent-new-line),
the bug is always triggered (or at least, it's been triggered for me all
the times i've tried).

Possibly telling: any line written above the point where i pressed M-j
is auto-filled correctly, and any line written below that point gets the
wrong behaviour.


Of course, the first thing comment-indent-new-line does is calling
comment-normalize-vars, so it seems Katsumi is on the right track.

BTW, after i trigger the bug in this way, setting paragraph-separate to
its previous value doesn't seem to have any effect: th problem's still
there.

Cheers,
jao
