It occurs to me that (at least for readline... and maybe also as a
general proxy for whether the rest should be done) detecting the IUTF8
terminal flag (which, properly, controls basic non-readline-based line
editing such as backspace) may be worthwhile.

(And maybe Readline itself should be doing this, more or less
independent of Python. But that's a discussion for elsewhere)
