I'm assuming that you're referring either to my comment about
(and pw (send-invisible pw)), or else to Kevin Rodgers' suggestion of
(send-invisible (or pw "")) ...

Unfortunately, neither one of these is particularly useful; neither one of
them prints any sort of message (not even 'Quit') to indicate that the
password is no longer being read invisibly, and the latter actually sends
something (even if it's just a newline) when the user tries to abort the
command -- Bad Thing.

I believe what we want is a slight reorganization of those functions;
unless they get heavy Lisp usage, it shouldn't cause much
incompatibility damage.  The attached patch (versus 21.3.1) causes there
to be no further prompt but rather the proper warning when the user quits.
I also added references to 'clear-this-command-keys' in the docstrings;
would it make sense to make that function interactive?
