Fix invalid url, generated by clojuredocs command.

Some IRC client have problems with urls, generated by clojuredocs command. So they include semicolon to url when higlighting like here: [http://clojuredocs.org/v/43;](http://clojuredocs.org/v/43;) E.g. pidgin and xchat do this. I think it's better to ommit semicolon or separate it from actual url by 1 space.
