Hi Arash
First thanks for looking into this
Two comments
1. Confirmed, you are right, but
2. I receive lately a lot of latex files, with very very long lines
(it seems that a lot of latex editor now support soft line
wrapping), emacs still struggles I use virtual-auto-fill-mode
from time to time but it is inferior than running auctex latex
fill commands. So mostly I run LaTeX-fill-section on those files,
and as this example indicates this can result in a sort of
catastrophe since emacs becomes idle but is then silently filling
the buffer with these
%
%
lines.
3. This is why I sent this report. It might be helpful if emacs
would just abort the filling process with an error message, but I
am not sure how this could be implemented
Regards
Uwe
