Yay! Welcome!

Working on darcs has improved my Haskell somewhat.  I still feel new to
the language though...

I have marked issue88 as resolved.  Gosh, that error message is kind of
unpleasant though; it would be nice to have something friendlier.
Something like directory 'a' does not exist!

Have also marked issue203 as resolved.

Good thought.  Perhaps you could make a function like
  getLongDarcsOption :: DarcsOption -> String
  -- I am horrible with function names; pick something reasonable

So that you can just say (getLongDarcsOption allow_caseonly).

This has the added benefit of avoiding stuff like head.
