[IronPython] IPCE and Mono 1.2 interactive interpreter sadness

[Anthony Baxter]

Hi Seo (and others).

IPCE on Mono 1.1.17 works really nicely in interactive mode. Backspace
works, ^D to exit works, the lot. On 1.2.2, however, it's a world of
broken. Backspace is just insane, ^D stopped working again... it's
pretty much unusable. I'm not sure whether this is a Mono bug (in
which case it should be logged) or a problem with the IPCE code. Can
you provide a more informed opinion?
