#2606: Backspace, delete, etc. don't work in ghci in HEAD

$ ghci
GHCi, version 6.9.20080912: http://www.haskell.org/ghc/ :? for help

Prelude> a^? [RET]
<interactive>:1:3: lexical error at character '\DEL'
}}}
When I pressed my Backspace key, the {{{^?}}} showed up. When I pressed
Delete, {{{^[[3~}}} showed up and ghci apparently thought I'd typed an
{{{'\ESC'}}}. Arrow keys didn't work either (also seemed to be mapped to
{{{'\ESC'}}} and {{{Ctrl-U}}} seemed to send a {{{'\NAK'}}}. However, when
I hit {{{Ctrl-Z}}} to suspend ghci and then brought it back to the
foreground, all the keys started working.
* everything works fine if I start ghci in a shell in emacs, instead of
in an xterm (in the latter, {{{$TERM=xterm}}}
* emacs sets {{{$TERM}}} to "dumb", so I tried executing {{{declare -x
TERM=dumb}}} and then starting ghci in an xterm, but the keys still didn't
work
* declaring {{{TERM}}} as {{{vt100}}} didn't work either.
* Ubuntu 7.10 with xmonad (I think 0.3), if that helps.
