Neither of which are standardized behavior so you'd need to use the  
attribute for Safari, the viewsource url for Firefox, and what ever  
feature was supported in Opera (is it?).

What Karl suggests on the other hand is defined behavior as per the  
HTTP protocol and the MIME type definition for text/plain.

I'm not sure we should be defining behavior that is against the well  
accepted HTTP protocol and MIME type standards.
