Hi, 

I debugged this problem to start with my commit

http://bzr.savannah.gnu.org/lh/emacs/trunk/revision/110817

The reason is that `add-comment' is wrongly reset for new line instead of
`in-comment' (`add-comment' is automatically reset after `in-comment' for
each line).

Fix comitted to trunk as r116025. This must also go into emacs24.x branch.
Which is the best way to make this happen?

Regards,

Starting from emacs -Q add the following to a buffer and put it in
latex-mode (I checked both AUCTeX and the builtin latex-mode):

% Again, we ignore the actual values of $\zeta_{i}$.
It is clear that $Z(G)=\angles{c_{i}}\cong \mathbb{Z}_{p}^{2}$ and $G'=\angles{b_{i},c_{i}}$.
Missssspeelllllled.

Run ispell-buffer.  I have to do the following to get ispell to work on
my system:

(setq-default ispell-program-name "hunspell")
(setq ispell-dictionary "american")

You will notice that it tries to correct G', when it should not (since
it's in math mode).  It also ignores Missssspeelllllled.  It seems it's
getting math mode backwards.  However, if the first line is uncommented
then everything works correctly.
