As long as we're on the subject, how about a seperate character to
eliminate your whole typeahead buffer -- newlines and all?  VMS uses
^X for this, ^U for line-delete, and ^X is like ^U if you are typing
to a read request -- i.e., you are not experiencing delayed echo.

In reference to the above, if delayed echo is implemented, ^R should
reprint the entire buffer -- not just the last line -- whenever echo
is being delayed.  I remember this from the Alpha Micro, and I miss it.
