I've decided that it was a mistake to use -E as the option for adding
keys encrypted, because it's better to use it as a fingerprint type
selector for the Pageant client side. That way it works the same as
command-line PuTTYgen, and also OpenSSH ssh-add (and ssh-keygen).
What spelling(s) to use instead for the option to add keys encrypted?
Obviously, the same ones I've just decided on for Windows Pageant;
there's no sensible reason to make them different.
