We certainly don't want that as a separate step -- my notion would be
to have Save As vs. Save As Encrypted.  Once you've saved something as
encrypted once, it keeps getting saved encrypted.  And then the
sudo-model of only entering a key if you haven't looked at anything
encrypted for some time interval.
