Remove module from context completion

[boris]

I propose to suggest in completion only modules the user already loaded into the context. The completion should look like this

Prelude Data.List> :m -
Data.List  Prelude

instead of this

Prelude Data.List> :m -
Display all 728 possibilities? (y or n)

I have already written a patch, but it requires addition of one function into haskeline library. Actually, this function can be put into ghci, but it fits more naturally in haskeline. I have created a ticket in haskeline trac  http://trac.haskell.org/haskeline/ticket/109

Sounds good to me (although I am no expert on this part of GHC). I assume we should wait until you have the patch in haskeline; then you can send us a revised patch for GHC if one is needed.

Thanks for doing it.

Haskeline has been patched, but slightly differently, so the patch will need to be adapted slightly.

Should be easy to do, so I've made the ticket high priority so we don't forget.

Applied, thanks!
