Subject: Alleged Rubout/Echo lossage

Rubout processing and echoing is sometimes wedged.
The following is quite reproducable:
Right where I have indicated a ^L, you can type without
getting any re-display or rubout-processing.
Things seem to get wedged quite often on the next
form after a toplevel call to LOAD.
I typed exactly the same and observed no lossage whatsoever.
Evidently, whatever you saw isn't so easily reproducible.
What was missing was that you had, upon ocasion, typed one extra
right paresn -- not that in your mail to me you had the correct
number typed in. Thus the lossage is observable (as KMP's eagle
eyes spotted) when you type the extra right parens.
Happily, I believe I've fixed the problem, and patched
it in the currrent LISP dump.
