Description

In RFC 2396, scheme does not include comma. 

      scheme        = alpha *( alpha | digit | "+" | "-" | "." )

However HtmlFormatter generates a link from x,://localhost/ because WikiParser.LINK_SCHEME matches x,.

See how stupid that regexp parser is, it couldn't see that I didn't want a range in that case.

:-)

Good catch!
