Line breaks on long class::method names.

I have created a patch that existed on the old php.net but not on the new one. basically it injects a hidden <span> after the "::" characters so the method name bumps onto the next line if the width is too large. See this screenshot: http://puu.sh/1LcK0 Are you guys happy with this solution? I nobody has came up with anything better as of yet so I'd like to commit this change. Thanks, Paul.
