Doesn't <br/> need a closing tag? (I've got *no* clue about XHTML)

Just replacing <p>'s with <br/></br> is ugly IMO, because we remove the 
information that a new paragraph is started. So we should only do that if 
we want a blank line, and not something else.

As for implementation, isn't this the same kind of problem as for 
closing a list item? (Guess I'll have to dive into pmwiki.php sometime 
soon.)

Oh, and at the moment, is it possible to a create new paragraph while 
inside for instance a list item?

One solution would be using a stack where you push things like '</p>' 
onto, and before leaving the list item you pop it.

But I guess this assumes a general structure where tokens are parsed etc, 
rather than *only* substituting regexps....

Speaking of which, how is '\' at the end of a line handled? Is the '\' 
stripped and the next line simply appended to the current variable 
representing the current line?

If this is the case, I don't understand why a '\' at the end of a line 
produces a space:
