Perhaps you're right, but as far as I can see the Emacs build system
does not yet tell us how to proceed with data.  It also has a unique
way of handling documentation, first putting it into site-lisp before
moving it to share/info where it should belong.

Looking at your revised patch, I still feel a bit uneasy about putting
data into the load-path.  I therefore proprose a revised revised (R^2,
if you will) patch, which I've attached to this message.
