I just typed up a whole email explaining why it would be better for
novice users if the process for this was not so complicated.

Then I realized that novice users should not be suppressing this
warning, and should instead be taking the extra call to
`package-initialize' out of their init-files.

As a result, I now wholeheartedly agree with your idea, and I've
attached a revised patch. Thanks for the feedback.
