[Maxima] emacs&maxima bugs

[Valery Pipin]

Hi!
I found some issues in emacs interface to maxima.
I'm using 5.13 and emacs-22-gtk on altlinux 4.0.
1)Uncomment does not work. It simply put additional coments marks instead.
This option is quite useful. Does not work for  me nor from keyboard nor from 
emacs menu.
2)Stop does not work. I think this option is designed to  temporarily stop 
calculation if it's needed for some reason. I don't know if it is really 
actual. On unix I can renice the process quite easily. 

kind regards
Valery
