WHAT?!?

Taking a look at the XEmacs in Ubuntu, I see that xemacs-packages is
_before_ site-packages in the search order.

What idiocy is that?  This is completely insane.  Whoever at Debian is
responsible for that ought to be shot.  XEmacs in Fedora does not have
this sick, sick load order.  Seems to be a Debian special.

Well, it is called auto_autoloads.el there...

You are not supposed to look at the return value of
unload-feature...  So it is to be used non-interactively.

Ok, so it seemingly does not work.  Pity.  Would have been nice.  I'll
have to experiment somewhat with that (could be that it is easy to
fix), but then the "canonical" way to "unload" will be

(TeX-modes-set 'TeX-modes nil)

if you are allergic to customize, and

M-x customize-variable RET TeX-modes RET

if you can survive it.  It will not be a true unload, but it will keep
AUCTeX off from the modes themselves.
