I redefined `TeX-how-many' to be equal to `how-many' in Emacs >= 22,
and added a workaround to make `TeX-how-many' return a number in
XEmacs and Emacs 21.  Thank you.

I can reproduce this in XEmacs too.  Do you mean that this doesn't
happen with Emacs 21.4?  Is "*TeX Help*" buffer colored as it should
be in Emacs >= 22?  Since `propertize' doesn't seem to have effect in
XEmacs, I'm thinking about setting `TeX-error-description-*' faces to
nil there, but I need to know whether we should do the same in Emacs
21 or not.

I added `(current-buffer)' to all `local-variable-p' calls with a
single argument.
