Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I have two problems with 21.2.

In a shell window the cursor sometimes just goes away.  As soon as I type it
comes back, but it is odd behavior.

Also in a shell, I used to be able to hit ^C^C to interrupt a subjob.
That no longer works.  But the keystroke is still bound to
`comint-interrupt-subjob' and the odd thing is if I do 
esc-: (comint-interrupt-subjob) THAT works.

Thanks,
