Comment (by Aviator):

 > Do arrow keys work with ghci in your terminal?

 Yes.

 > If you run the following command in the shell, does it clear the screen?

 Yes.

 > If you run the following command, press the Home key, then press Return,
 what happens?

 Pasted output:

 {{{
 aviator at aspire:~$ ghc -e getLine
 ^[OH
 "\ESCOH"
 aviator at aspire:~$
 }}}

 > Finally, the haskeline library (which handles line-reading for ghci) has
 had several updates since ghc-6.10.4 was released.  Can you confirm
 whether this problem still occurs with the most recent version of
 haskeline?

 Okay. I ran ghci-haskeline and the control buttons work!
