Summary: Bad message for duplicate arguments

Initial Comment:
The following program:

Module main where
  f x x = 3

gives the following error with GHC/HEAD:

baderr.hs:3:
    Conflicting definitions for `x'
    in in a pattern match

(as well as the obvious error because there's no main 
function)

Note: 1. This error message is confusing (according to 
SPJ).

2. "in in".
