I left it vague to handle some variety.  Something to add/delete users is
nice.  Something to change password in place is nice.  Something that given
a user and plain text password and everything else Dovecot needs when using
it as userdb, and would output to stdout the line contents that would go
into the file, would do the job.

I want to avoid re-inventing the wheel.  If there are no wheels, I guess
I'll just look up the salted-MD5 format details and do it.
