In a previous discussion, I suggested adding a prompt type for
"continue".  The text would then be something to the effect of "Please
insert your token.", and it would be up to the prompter implementation
to convey how to continue.  For instance, the POSIX prompter might
display

  Please insert your token.
  Press enter to continue:

and the GDM prompter might display a dialog saying "Please insert your
token." with continue and cancel buttons.

Existing prompter implementations might do something suboptimal, but not
entirely broken.
