cli interrupts and emacs

[Patrick G. Sobalvarro <PGS @ MIT-MC>]

Correct me if I'm wrong, but once upon a time I seem to remember having
Emacs uderstand that I'd gotten my screen bashed and redisplay it after a
CLI interrupt as soon as I typed a character.  This was a nice feature,
something Twenex emacs couldn't do because of the way tty messages work
there.  Well, it doesn't work anymore.  After a CLI interrupt, when I
type characters, my Emacs doesn't redisplay at all.  It doesn't do anything
until I type something like ^L, which is an ECHOIN break character.  Is
ECHOIN broken?
