[ESS] polymode, tangentially related to ESS

You're right, the font changes are no doubt due to the default
configuration of Aquamacs.  But isn't that part of why you have
different major modes?   For R code you might want a monospaced font,
for markdown a variable spaced font, etc.   Ensuring all the modes use
the same font just papers over the real deficiency, the fact that the
mode is associated with the entire buffer instead of a region.

I stumbled across a page describing Multimode editing in emacs [1].
(polymode isn't on the list yet.)  The oldest multi-mode
implementation [2] has a good discussion of using indirect buffers and
the major surgery it would take to associate mode with buffer range.
This would probably be a very daunting task to muck about in the emacs
internals at such a low level but I think it would be the "right" way
to do multimode.

No matter, I'll go fix my fonts.  Vitalie, I'll submit screenshots in
github just so there is a record of this issue.
