[darcs-devel] [issue1026] Darcs trouble

Jason, indeed we were just asking ourselves that question, why do we consider it
a bug for an 'extra' patch not to commute past the list of skipped ones.

I agree that we should augment our debugging to say more about commute failures.
  Could something like commuteFL2 just become the new commuteFL?  Could we just
upgrade the commute functions to always return Either?  Would it maybe be
appropriate to upgrade to a MonadError (p,p) m => m 
(modulo witnesses)?
