#1792: -ddump-minimal-imports breaks qualified imports (import...as)

-----------------------+----------------------------------------------------
When using the -ddump-minimal-imports option on a Haskell file, it breaks
qualified imports.
Ie, suppose one has a line in a file thus:
import qualified Data.ByteString as B (putStr, readFile)
Using -ddump-minimal-imports will give you something like this:
import Data.ByteString(B.putStr, B.readFile)
There are 3 things wrong here:
#putStr and readFile should not be renamed thus, as obviously
Data.ByteString has nothing under those names
#Data.ByteString is no longer being imported under a different name, so
all function uses relying on B.putStr etc. will break
#Finally, it's just ugly to have no spaces between the last letter of the
module's name and the opening parenthesis.
I see this behavior under GHC 6.6.1, and asl of #haskell tells me he
duplicated the import problem using GHCi version 6.8.0.20071019.
