Okay, here is an attempt at adding control-C support for \prompt and
\connect. It was reasonably straightforward. I did have to teach
simple_prompt_extended() to add a newline after a cancellation when
"echo" is true.

I think that's it for psql. After a quick glance, I didn't see any
other obvious candidates for control-C support, but I'll look a little
closer to be sure.
