Well, you should have probably re-read that thread's opening message.  I'm
talking about a common function of right Alt key: it temporary (while pressed)
disables the current layout and switches to English layout.  I guess _that's_
why right Alt doesn't work as Alt in Emacs for Lennart Borgman.  I don't really
know, though.

Now I'm talking about GNU/Linux, where Emacs is working incosistently with
the rest of the system.  It disregards Mode_switch (i.e. right Alt when
working in the layout-disabling mode I described above) when working with
LEIM.  E.g., in Gaim, while using the Russian layout, I can type [right alt]-ъ
to type the closing bracket, because Russian letter `ъ' is on the same key
as the closing bracket in the English layout.  In Emacs, typing [right alt]-ъ
still produces `ъ'.

That's OK, but they don't work the same for Lennart, right?  I'm arguing,
that since it is system setting, Emacs shouldn't override it.
