Prefix negation

[John Peterson]

Pardon me - I was explaining the intuition rather than the
translation.  -x is translated to negate x but as far as fixity, you
have to appeal to the 0-x notion.  The basic idea is that the
precedence of unary and infix - are the same in this way.

I did a brief search of the old haskell committee mail, but I don't
have the definitive message about unary minus around anymore as far as
I can see.  We seem to have finally given up on the debate by Haskell
1.3.
