START /K ...

#1
If I issue
Code:
start /k dir
I get a new TCC (new console), DIR is executed, and the STARTed TCC hangs around. I figure that's correct behavior.

If I issue
Code:
start /k dir /p
I get a new TCC (new console) with DIR in progress, sitting at the /P prompt If, in that new TCC, I press <Esc> (to end the DIR command) the STARTed TCC exits. That doesn't seem right.
