fill-paragraph and LaTeX comments

[Franck Pommereau]

Hello all,

I have a problem with fill-paragraph (M-q) in LaTeX mode.
For example, consider this text:

%
very long line that should be filled

If my cursor is in this line and I fill it with M-q, I get something
like:

% very long line
that should be
filled

So, some of my text is now commented, which is really a problem! The
same occur with $$.
I've tried to customise paragraph-separate to "[ \t]*\(%.*\)?$" and
similar regexps but this does not help.

Can anyone help me with this?

Many thanks in advance!
Franck
