How about throwing an error the moment you define a set of options 
that create this potential ambiguity?  ;-)  (i.e. force you to define 
--string1 and --string2 instead of --string and --string2)

(Either that, or have an option to turn off ambiguous guessing, and 
throw the error unless you've turned it off.)
