Hi François,
looking at lshort.pdf, the list of characters to exclude would be like
this:
\begin{tabular}{@{}*{4}{cl}@{}}
\hline
\`o & \verb|\`o| & \'o & \verb|\'o|
& \^o & \verb|\^o| & \~o & \verb|\~o| \\
\=o & \verb|\=o| & \.o & \verb|\.o|
& \"o & \verb|\"o| \\
\hline
\end{tabular}
I can fix this with a patch I proposed here:
http://lists.gnu.org/archive/html/auctex/2017-04/msg00047.html
Applied locally, it looks like this:
What do others think? Is this the way to go for AUCTeX?

Thank you for the corrections in the last Auctex version, but openning an old file, when I typed diacritical mark using TeX command for accented characters, I can see that the problem remains for all these commands; examples: m\^eme, \'etant, r\'eit\'er\'ee, S\=uryad\=asa and a lot of others... So, nowadays, using xelatex and unicode we can avoid this... But for people using a basic 7bits keyboard it could be nice to correct also these commands...

I think that start writing tests for fontification may be a good idea
at some point ;-) Fontification tends to be often broken and it's
hard to understand what was actually broken and what's the status-quo
that we want to preserve.

Are those valid commands? When I try to define them using

\newcommand{\^o}{dach o}
\newcommand{\~o}{tilde o}
I get the error

Thanks for your patch, it looks much better. I think the only thing
missing is when you have a character with punctuation syntax after \
like \"o, \^o or \~o. What do you think about a variation like this:

We can extend the exclude list if other characters appear.

Following up myself, the patch was not good enough. Here a test case of
fontification right now:
Applying this patch:
--8<---cut here---start->8---

[AUCTeX] fontification question
Bonjour, I added to my .Xresources file: "Emacs.font-latex-sedate-face.attributeForeground: indianred2" in order to have all LaTeX commands in indianred. But when I use a command like \- for discretionnary hyphen, the whole word after the \- command is turned into indian red, ie. the fontification is not applied only to the command (which is actually in red). For instance: anti\-constitutionnel: \- is in red and constitutionnel in indian red. Is there a way to avoid this?
