Ctrl-C in cabal repl shouldn't exit the repl (just like GHCi)

[adimit]

When running ghci I can use Ctrl-C to interrupt actions that have obviously gone AWOL, or cancel a long running computation without entirely exiting GHCi itself.

This does not work if GHCi was started via cabal repl. If cabal repl were to trap SIGINT and pass it on to GHCi, which would do the right thing with it, that would make my life a lot easier.

Alternately, a different way to cancel a computation without (expensively) exiting the repl should be provided.

EDIT: disregard this, I clicked the button twice by accident. The actual version is #1610.
