slightly incorrect error message

8:51am moussor:ResUsage/ cat > Foo.hs
foo s
  | [a,a] <- s = Nothing
8:52am moussor:ResUsage/ ghc Foo.hs

Foo.hs:1: No 'main' defined in module Main

Foo.hs:2:
    Conflicting definitions for `a'
    In a pattern in 'do' binding


should really not mention "do".  The last line should probably read "In a
pattern in a guard".
