I hunted down the -1 + 10 == -11 bug.  I came up with a fix, but I'm not
sure how apporpriate the fix is, which is why I'm submitting it as a
patch.  The problem was that in Prim.hs all the symbolic unaries were
being listed alongside the named unaries, and the unaries in the
precedence table were being overwritten by the universal-precedence
named unaries.  

I fixed it by adding a new "associativity", "spre" (symbolic prefix).
This is for prefix things that are listed in the precedence table in
Parser.hs.

Please look over it.

Luke

It looks sane.  We eventually want to regenerate the whole table
using the precedence traits (without hard-coded tables in Parser.hs),
and this needs to be redone when that happens, but for now it should
work.  Applied!

Thanks,
