So you want to make `TeX-doc' work in non-AUCTeX buffers. OK, it would
be harmless for ordinary users and beneficial for users like you. I
think AUCTeX can accept your idea. Here are some comments for your
proposal:

I basically agree with your idea to use symbol `t` for "all modes". In
that case it isn't much meaningful to "add" t to the mode list; the rest
of the elements are totally useless. Instead of a list, we can just have
a single `t' for that purpose. Then we can simplify the conditional as
(or (eq t (nth 1 elt)
    (memq major-mode (nth 1 elt))
How about this idea? (If you are fine with it, please adjust the doc
string as well.)

Don't worry, you are following the right path. :-)
