If so, the WMs are broken.  The WM should just say no: "you're
maximized, I just set you that way, and that's that---shut up and get
to work."  See the ICCCM, and also the Xt shell spec.

Why this gets into a loop I don't understand.  There should be a
flash, then XEmacs will docilely stay maximized.

Re fixing: I guess there must be some protocol for maximizing by now
so that XEmacs can find out that it is in fact "maximized", or we can
use a heuristic of matching the size the WM specifies to the size of
the screen (note that this *will* be heuristic, because XEmacs cannot
know if there will be decorations or what size they are in this state;
I guess we can query the Shell widget for its size, which might be
more accurate.)

If the window size is specified in characters and the size of the
characters change, it should.  I *want* my window to stay 80 columns
wide when I change from a 10pt font to a 14pt font, or vice versa.

I know that modern text widgets (by Procrustes[tm]) don't care about
that, but I do like it that way, and I don't see why XEmacs should
change this behavior unless the users *want* their lines wrapped or
truncated differently just because they changed font sizes.

Which is in character cells.

Precisely.  The ICCCM doesn't allow the client to resize its toplevel
windows.  As far as I can tell, XEmacs does not try to do so.
