Ok, I'll set those faces to nil then.  One will anyway able to select
a custom color, if `propertize' works (and it doesn''t work for me
even with default faces in XEmacs 21.4).

Uh, strange, I'll check it out with XEmacs, but I'm sure this doesn't
rise errors with Emacs 22 and 23, just tested.

Since a few months ago, we have a test suite under the tests/
directory, see also
http://git.savannah.gnu.org/cgit/auctex.git/tree/tests/latex  This
allows developers to verify whether a commit broke a feature for which
a test suite has been set up.  Adding a test suite for your feature
isn't mandatory, but it could helpful as the only current test is also
about tables.  If you feel like writing a test to check parsing of the
table specifications, do it, that's all ;-)

Bye,
