Now I need to know how that helped.  Do you used a non-default mode?
The change had 2 parts and I should have split it for testing.  It
fixes the window sizing and constructors.

Try "<newline>~b".  It is an old bug that Ctrl-Alt-ESC (and Ctrl-PrtScr)
are misconfigured by default.  But I think the misconfiguration is the
same for vt.  There are about 3 layers of options that have to be set
to "enable" or not set to "disable" to enable these keys.
