Hello,
The TeX mode introduces a new bug in Emacs 23.1 that was not present in
22.3. This bug is not present when using AUCTeX - I am referring to the TeX
mode that comes with Emacs.
Specifically, when I want to manually re-fill a paragraph that has an empty
comment line right before it, the first line of the paragraph is "bumped up"
into the comment line. This "breaks" the document, since of course comment
lines do not appear in the document LaTeX produces. Here is an example:
===
%
Aaa aaa bbb bbb. Aaa aaa bbb bbb. Aaa aaa bbb bbb. Aaa aaa bbb bbb.
Aaa aaa bbb bbb. Aaa aaa bbb bbb. Aaa aaa bbb bbb.
===
Placing the cursor on a sentence and then manually re-filling triggers the
bug. It seems to be introduced by a change on line 1052 (of the new
list/textmodes/tex-mode.el). The new line says:
===
(setq paragraph-separate
(concat "[\f]\\|[ \t]*\\($\\|"
"\\\\[][]\\|"
===
The old line (which had a different number) used to say
===
(setq paragraph-separate
(concat "[\f%]\\|[ \t]*\\($\\|"
"\\\\[][]\\|"
===
Reverting just this line to the old one fixes the problem.
Thanks,
Dan

This seems to have been done deliberately. Stefan, could you check your
change?

* textmodes/tex-mode.el (latex-mode): Remove % from paragraph-separate
so that M-q can fill comments.

M-q does fill comments without the change. It just doesn't mix them with
non-comment text (which is probably what you want anyway).

It looks like this commit was mistaken: the problem it introduces is
too serious. Please revert it if you get to it before I do,
Stefan
