I originally thought that this was the way to go, too, but in
researching the issue, I discovered that somewhere around B19 (I
think), the choice was made to *not* have AltGr generate Meta because
AltGr is used on international keyboards to generate the standard
shell characters, like '[]', '{}', etc., that are provided in
triple-overloaded keys.  Ah, yes, here is the description of the issue
from the changes to B19 in the FAQ:

   Alt Gr-key behavior has been changed in this release. The left
   alt-key still produces ESC-key sequence. The right alt (Alt Gr)-key
   now produces characters according to national keyboard layouts.

I think if you simply reverted AltGr to Meta again, international
users would be stuck having to make their own patches (as they did in
the past, I seem to recall reading) to generate shell characters.

If I've summarized this issue incorrectly, I hope some international
users will pipe up!
