ctrl-C in read causes exit from REPL

[kamahen]

If I interrupt a read with ctrl-C, the various debug options either do nothing (e.g., "continue") or raise "abort" or "exit". Both of the latter exit from the top-level. I'm pretty sure this is a somewhat new behavior, but haven't tried to track down when it started.

I rebuilt with the latest commit - 0a145e4 - and got the same result (except for the version # of course).
