:i gives bogus type

[pimlott]

Observed by me and Ketil Malde
<ketil+haskell@ii.uib.no> in ghc 6.2.1 and 6.2.2:

Prelude> let (...) = (.) . (.) . (.)
Prelude> :t (...)
(...) :: forall c a a1 a2 b.
         (b -> c) -> (a2 -> a1 -> a -> b) -> a2 -> a1
-> a -> c
Prelude> :i (...)
-- ... is a variable, defined at <interactive>:1
(...) :: forall a a b c a.
         (b -> c) -> (a -> a -> a -> b) -> a -> a -> a -> c

:t is correct, but notice that in :i, the type variable
a is repeated.

PS.  There is no bug category for ghci.
