Thanks, but I'd like to avoid changes in keyboard.c on behalf of input
recording issues, unless such changes are really a must.  In this
case, we already have 2 facilities to deal with unwanted repeated
recording of keys:

  . a Lisp program can bind inhibit--record-char to a non-nil value to
    avoid recording input events while some Lisp form is executed (you
    can see an example of using this in quail.el:quail-start-translation
  . a Lisp program can push onto unread-command-events a cons cell of
    the form '(no-record . KEY) to avoid recording KEY more than once
    (you can see an example of using this in
    cua-base.el:cua--prefix-override-replay)

Can you use one of these facilities to solve the issue in Calc?  Note
that you will need to build Emacs from the Git master branch to be
able to use these facilities, they are not available before Emacs 27.

Thanks.
