That pattern will match as long as you don't force it to leave 3
characters after the negation.  Given the word description:

   descript.ion <-- won't match because \(ion\)[EMAIL PROTECTED] matches AT 
that point
   description. <-- works just fine because there's no 'ion' at the
                    current position

   /\i\+\(ion\)[EMAIL PROTECTED]>

The above pattern will do what you wanted since it forces there to be 3
more characters and the end of word when you try to match 'ion'.
