No, it does in fact stop completion on every character typed (unless I've done
something wrong and it only *sometimes* works, but it does work 100%
consistently for me). I'm not sure the feature would be popular enough to
warrant an entire regex to specify the 'stop' characters, and at any rate, I
don't think I'd be up to the task.
