[AUCTeX] format region without auto-fill

[Michael A. Gilchrist]

Hi All,

I am using AucTeX with XEmacs.  I would like to use the format-paragraph and 
format-region options so that all of my lists, paragraphs, etc have some 
sensible formatting.  I do not, however, want the lines to be wrapped using 
auto-fill (indeed, I don't use auto-fill at all).  Is there a variable I can 
set so that the lines are not cut off.  One that comes to mind would be to 
enable autofill but then set the max line length to infinity (or something of 
the sort).

Any suggestions would be appreciated.

Thanks.

Mike
