I did not know this! Thank you for sharing your knowledge. I chose to
use the "unless" form so I would know if it ever failed to load.

That's good to know. I guess this module didn't do the "autoload magic"
that some modules, like magit, do?

Aha! Yes, that fixed it. I was so close! Thank you for taking the
time to help me finish this up. I am now happily using jl-encrypt.
It's automatically signing my email and protecting me from sending email
in cleartext when I should be encrypting it otherwise! Great stuff.
Patch incoming! :-)
