    Will do.  For now, I have accepted yours.

    That is of course exactly what I did.  A simplified version that
merely accepts C-f and C-b and moves forward and backward through the
echoed dots is attached.  I have had, however, to insert my own cursor
by hand.  The problem is that the echo of the password is produced by
message and message doesn't seem to call the minibuffer-setup-hook you
taught me about.  (If you enable cursor-in-echo-area, the cursor
appears but sits at the end of the line.)

    This is what I did, along with changing the nested ifs to a cond
for readability.

    Read password doesn't do anything with C-y; it just goes in as an
element of the password.
