Fixed setting "tainted"

Browse source 
Set "tainted" if and only if any character was read from the device.

Ctrl-t is no longer sent to the device on exit, so the trick to avoid
its echo is not necessary.

Characters read from stdin don't directly affect output, so they
shouldn't enable "tainted".
