Yes, that's more secure.  Now that you mention it, perhaps we did fix
the aggressive password prompting?  I seem to remember adding a cache at
some point...

Anyway, having to enter a password for (say) sending email, even if your
SMTP server isn't password-protected (as you have to do with
.authinfo.gpg) isn't particularly ideal.

So I think the .authinfo.gpg concept isn't a good thing.  (But
encrypting tokens in the .authinfo file might be.)

And perhaps the password token in .authinfo should always be obscured,
at least, to avoid accidentally spilling the passwords (visually) if you
do a grep .* or something.  (This is what all the other
password-hoarding applications like Firefox, Chrome, etc do by default.)
