Well that's why I suggested that it be limited to individual text  
nodes, not to text that crossed into (or were broken by) other  
elements. Even with that limitation, it would still be powerful and  
very useful (especially if you could use regular expressions).

That sounds like like you just refuted your own argument. If a line  
break is turned into a space in the DOM, and that space is selected  
with the pseudo-element and not displayed, then what's the problem?

Agreed...

I find myself often wishing for it, especially when styling HTML that  
I can't edit myself.

Well, sure, I'd like both too. But if I were to choose which I wanted  
more, it'd be the more powerful thing that fulfill do both roles if  
need be.
