What is the exact reason that prevents fixing post.trm (and maybe other
broken terminals) so that it would correctly update term->xmax and
term->ymax?  I would imagine that it wouldn't be terribly difficult to
change accordingly the values of these two variables when the postscript
internal canvas grow.  Is it somehow a problem with backward
compatibility?

I wonder if the problem with the inconsistencies between different
terminals and backward compatibility is so severe that a new global
option "set terminalmode {old|new}" is needed.  I believe that option
would be quite horrible from the maintaining point of view.
