Improve the rendering of the wiki syntax for citations

[cboos]

A little thing, but looks nicer IMHO

blockquote p { margin: 0 0 1em 0; }
blockquote.citation { 
 margin: -0.3em 0;
 padding: .5em 0 0 .5em;
 border-style: solid; 
 border-width: 1px 0 0 2px; 
 border-color: #b44;
}

I agree that this patch improves the visual separation of comments, but the new colorful ticket design is confusing me even more now. ;-)

Well, the current .css for citations is not that bad.
What is needed though is to better take into account the white space around the citation.

e.g.

----
someone said:
> this or that

That's a good idea!

> this is another citation
----

currently renders as:

---

someone said:

this or that

That's a good idea!

this is another citation

---

There should be a visual clue showing that there's a blank line between That's a good idea! and > this is another citation, but this should must rather be done at the wiki parser/formatter level.
