[issue1294] Management of KeyboardInterrupt in cmd.py

I am not sure I understand: currently Ctrl-C generates a
KeyboardInterrupt, which can be caught by the  application which can
then decide how to proceed (in particular it  can start another command
loop or exit with a meaningful message or anything else).

This patch would suppress KeyboardInterrupt and thus interfere with such
applications. Or am I missing something?
