It's dependent on the ordering of the PAM messages with the
conversation struct.  INFO first will probably work, PROMPT_ECHO.*
probably won't.

It sort of does but not in the general case.  The way it currently
works with only one prompt per round was required for SSH1 TIS but not
SSH2 keyboard-int.
