[Moin-user] Best way to disable 'short form' interwiki links?

[Pixologic Mail]

In other words, I want to make sure that 'SomeName:AnotherName' is  
_not_ taken to be an interwiki link; such links will only be given  
manually (i.e. wiki:someinterwikilink), since we need the ':'  
notation for a previously existing convention.

There's no apparent way to disable this in the config file. I'm  
assuming for the time being that I'll have to go in and hack the "big  
ugly regular expression", but was wondering if anyone could suggest a  
more elegant way to do this.

Thanks,
Ken
