Alternative fix for #384

The bug with emphasis syntax clashing with URLs did still occur with
protocols different from http or ftp. This patch might be a better
solution.

I had to use [^\x00]* instead of .* - for some reason the later won't
work properly in this case. It means people won't be able to use ASCII
NUL characters inside an emphasis.

The other thing that won't work is this;

Won't work: //semi colon here>://

People will need to make sure there is at least a space - this will work;

Works //semi colon here>: //
