Re: [nbusers] Intermittent errors when validating JSPs.

We should probably disable JTidy for JSP's; JTidy chokes if it sees  
tags it doesn't recognize - and that includes all jsp tags. There's a  
way to pass in a list of ignore-tags to jtidy before a scan but we're  
not using it. It would be better if jtidy was enhanced to handle jsp  
files properly (this has been requested on the jtidy list a few times).

The reason you get a blank preview is that when jtidy encounters an  
unknown tag it exits out without producing a marked up version of the  
source, so we're diffing the old version and the new empty/blank  
version.
