Not quite right here Herb... The thing is that some places in TeX you can  
use pretty much any character you like and it'll be fine. One of these  
cases is when trying to input a file name where an otherwise dangerous  
character like underscore would usually require math mode. Another is when  
you try to do weird stuff like \csname Xyz{$_}&*\endcsname (yes, this is a  
legal csname!).

The problem here is that with the redefinition of \includegraphics, the  
underscore is all of sudden just used for regular typesetting and it  
promptly asked to be put in math mode.
