I can attest to that. Nice going Judah!
$ cabal update
$ darcs get http://code.haskell.org/~judah/ghci-haskeline/
$ cd ghci-haskeline
$ cabal install
and I have a GHCi on Windows that can do completion, history search, and
exits when I hit ^D. That's made my day.
BTW, your LICENSE file looks like it was copied from the GHC source tree,
it still has various references to GHC and the University of Glasgow.
