I'm not sure I understand. Are you saying that you can't use
backspace/arrows/etc when the getLine command itself is waiting for
input? But otherwise at the Prelude prompt, where you type in the
commands, everything behaves fine?
If so, that is normal behavior for the getLine function.
For what it's worth, while ghci has behaved this way for a long time
(since at least 6.4), hugs seems to work more nicely in this regard. In
hugs when you getLine it seems to switch into cooked mode so you at
least get backspace etc.
