Workaround for sendtorepl and ghci

Judah, the author of haskeline, says:

"This was probably caused by a bug which has been fixed in the latest
release of Haskeline (0.6.1.6).

That fix should ship with ghc-6.10.4"

In the meantime, he gave me this solution, which works here:

cabal update && cabal install ghci-haskeline

Then, you should not interact with your 6.10.3 ghci; rather, you should interact with the executable ghci-haskeline, which is probably here:

~/.cabal/bin/ghci-haskeline

So now, when I start my screen session that I plan to interact with, I use this line:

screen -S haskellSession -t haskellSession ~/.cabal/bin/ghci-haskeline

Ghc-6.10.4 should not require this simple workaround.
