I am using AUCTeX (how could I do without it? ;-)), but it does
not (really) work for me, as you can check with:

--8<---------------cut here---------------start------------->8---
\textem{example}  % `font-latex-sedate-face'
\em{example}      % `font-latex-italic-face' on `font-latex-sedate-face'
--8<---------------cut here---------------end--------------->8---

The only difference is the italic applied on the same face...

And I just read a message from Ralf:

    `----

In fact, it would find it nice, would the LaTeX keywords be
highlighted differently than the TeX ones, or as well from
unknown ones (would I import a ConTeXt document!)...

The same applies for the environments: it'd be nice if the
default ones (`document', for example) would be different than
my own (like `indentated-par').

Best regards,
  Seb
