Prevent trailing URL punctuation from being parsed into URLs

[ZiNgA BuRgA]

I'd be surprised if there wasn't any difference, since the community forums typically run the latest stable version (not development version).

Arguably, the automatic URL parsing also has some issues with brackets and similar, but it's also difficult to really say what's correct, since URLs often do have punctuation in them.  Omitting trailing punctuation means that the parser has to do some more heuristical analysis of what's there...
