#9 Behaviour of ctrl+c in isql

[Kjetil Kjernsmo]

A simple feature request: I've noticed that the mysql and psql command line
clients behave differently when ctrl+c is hit: with mysql, the client exits,
with psql, the current query is stopped, but the client doesn't exit.

I feel that the psql behaviour is much nicer, but isql exits like mysql. So,
my feature request is that isql should just stop the current query, not exit
when hitting ctrl+c.
