Thread:Support/Suggestion: Add this CSS to MediaWiki:Common.css

I would suggest adding the following CSS to MediaWiki:Common.css.

What it does is that it adds an icon to the /qqq message space; I added it on Meta and it works there. The reason I did that was that I don't think the difference between an actual documentation message and the "There is no documentation for this message" message is big enough. If the documentation is short (one line), it is difficult to notice that there actually is documentation. This CSS snippet adds an "Information" icon to the message only if there is a message there.
