Thanks for the patch. I see one further improvement:
in the spirit of the DRD's, you may (for instance) see all symbols
which need the wasysym package as a group. So it is better to replace

        (drd-group latex-symbol%
          ...
          agemO
          APLbox
          APLcomment
          ...)

        (drd-table latex-needs%
          ...
          (agemO ("wasysym"))
          (APLbox ("wasysym"))
          (APLcomment ("wasysym"))
          ...)

by

        (drd-group latex-wasy-symbol
          agemO APLbox APLcomment ...)

        (drd-rules
          ((latex-symbol% 'x) (latex-wasy-symbol% 'x))
          ((latex-needs% 'x "wasysym") (latex-wasy-symbol% 'x)))

Notice that we might have to add a function which finds the *list* of
packages needed by a symbol (or command) instead of *the* package.
This should not be hard to do with the DRD stuff. Alternatively,
the right-hand side of latex-needs% may be a list, as you do.

Do you have a christmas tree TeXmacs file (or several ones)?
This would be very useful indeed...

Yes they do. By the way, we should one day put those \newcommands in
a DRD of TeXmacs-LaTeX-extensions (so that much of tmtex-preamble.scm
will disappear).
