 I am rather indifferent too about it. I agree with Ben that the shorter
 warning seems more user friendly, yet I think Simon is right that it is
 incredibly rare to have more than one redundant clause in a match (I can
 only imagine it happening as a copy-paste error) so I don't think it
 really makes a big difference.
