[WikiEN-l] space beneath headings

[tarquin]

this issue has raised its head again on the manual of style page. And it 
still bugs me that we're mixing up presentation with semantics.

recap: the curent situation is this:

== heading ==
Text: there will be little space between this and the heading

== heading ==

Text following a blank line. There will be a gap between this and the 
heading

So a quick question:
1. under what circumstances do we *definitely* need space between a 
heading an the following content?
and
2. under what circumstances do we *definitely NOT*?

The only one I can remember is that in tables (countries, elements, 
etc), we want *no* space.

any others?
because if not, we can resolve this problem with CSS:
h1 , h2 etc { usual space }
table h1 , table h2 etc { no space }
