 	That's what this whole conversation is about.  Someone linked to 
a post by "jon at", whoever he is, who said it doesn't matter if the 
closing tag is there or not.
 	Seems sort of shaky to me, and doesn't stop the situation where 
there are spaces at the front, but I guess that happens less.
 	The real answer is that people have to be careful what they do 
with source.
