Underlining problem in code

When I type this:

hello:bfewf

in FoldingText, it gets underlined (unlike normal code). For some reason, it seems the colon is causing the underlining.

Why is this happening and how do I get rid of this?

This is happening because that text is getting recognized as a generic URI: http://en.wikipedia.org/wiki/URI_scheme <scheme name> : <hierarchical part>

I know in this case its not what you mean, I think your best bet is to put a space after the colon.
