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,
