[AUCTeX] Specifying custom verbatim commands?

[Geoffrey Alan Washburn]

Hi, I'm using the fancyvbr LaTeX package and I've defined # # as 
verbatim delimiters.  Is there any way to configure AucTeX to know that 
it shouldn't break these when I try filling a paragraph?  There seems to
a way to specify verbatim blocks with a prefixing command (like \verb| 
... |) but I don't think this applies when there is no prefix, does it?

Thanks.
