I've included both changes, to doc and the the html export in the attached
patch, now with properly commit message including the TINYCHANGE.

I would like to also figure out why (still can't track it down right now)
if you don't do the settings via (org-html-mathjax-options) you get
orgmode.org's hosting of mathjax.js via HTTP. It would seem wiser to either
host this under HTTPS so that the loading of mixed-content is not blocked
when using HTTPS or change that to also using the cdn.
