In the interest of getting you an answer quickly, I only tested it for
about 5 minutes, but in all of those tests, I can happily say that it did
what I wanted it to do.

It certainly did in my brief tests.

Thanks for that emacs-fu.  (Although I wonder if I want 'ConTeXt-mode-hook'
intead of 'LaTeX-mode-hook'.)

Regardless of what hook I should use, this version of your patch seems to
work very nicely.  Thank you for all the time you have put into this.
