[Orgmode] Context sensitive M-q

[Thomas S. Dye]

Aloha all,

I can't break myself of the M-q habit and often call fill-paragraph  
inside a source code block while the buffer is in Org-mode.   
Typically, this rearranges the source code in an undesirable way.  Is  
there some way (other than breaking the M-q habit) that I can protect  
source code blocks from Org-mode's fill-paragraph?

All the best,
Tom
