When collapsing margins, the most negative margin given is deducted from 
the most positive one. I.e. if a <p> is followed by a <ul>, and the <p> 
has a margin of 1em and the <ul> one of -1em, the two cancel each other out.

The bad thing is that two <ul> following each other will have a net 
margin of -1em, making them overlap. (IE will indeed produce the 
overlap. Firefox does not. I'm not sure which of them is right, but it 
confirms that using negative margins is probably not a good idea.)


I see to reasonable decisions at this time:
1) Punt on the issue, and always have that empty space between 
enumeration and normal text. That's how HTML was designed after all.
2) Detect the situation, and insert a paragraph with a 0.1 pixel height 
between adjacent <ul>s (and anything else that's paragraph-like in HTML 
but isn't in PmWiki). It's an ugly hack IMNSHO.
