	version=3.0.4

Emacs 22 has a new feature to display exponent text with an exponent
font in TeX-mode, but it doesn't work right: in the following line,
"{-9}$ blah.}" is displayed in exponent instead of just "{-9}".

\foo{blah $10^{-9}$ blah.}

There is no such bug in Emacs 21 since the text is shown using a regular
font.

In GNU Emacs 22.0.50.21 (i686-pc-linux-gnu, GTK+ Version 2.8.18)
 of 2006-06-17 on pacem
X server distributor `The X.Org Foundation', version 11.0.70000000
configured using `configure '--with-gtk' 'CFLAGS=-O0 -g -Wno-pointer-sign''

Thanks,

That should fix it:

2006-06-17  Ralf Angeli  <angeli@caeruleus.net>

	* textmodes/tex-mode.el (tex-font-lock-match-suscript): Remove
	superfluent part of regexp for brace matching which is handled by
	`scan-lists' call.

This patch works fine, thanks!  Want me to install it?

Yes, please.  We have been using the proposed regexp in AUCTeX for the
same purpose for several months now without a problem.

BTW, you don't need to mark the change log entry with "tiny change".
I signed papers for Emacs.  But I have to inform the copyright clerk
that my email address changed.  I will do this right away.

Ok, installed.  Thanks again!

Yep, I had checked beforehand.

Also, the copyright assignments file lists you as ``Ralph Angeli'' for
the Emacs assignment and ``Ralf Angeli'' for the AUCTeX assignment.  I
don't know if that's a mistake or if both names are correct, but having
just one would probably be a good thing.
