I have the interwiki prefix m-w: pointing to the Merriam-Webster Online Dictionary (mw: was taken by MediaWiki.org, of course), more specifically http://www.merriam-webster.com/dictionary/$1 . I discovered that the pipe trick doesn't work with this prefix, i.e. [[m-w:verisimilitude|]] doesn't expand to [[m-w:verisimilitude|verisimilitude]] as I expected, but to [[m-w:verisimilitude|m-w:verisimilitude]]. Other interwiki prefixes without dashes do work, i.e. [[w:Homeworld|]] does expand to [[w:Homeworld|Homeworld]] as expected.
