Yet another windows bug

[chris at umcp-cs.UUCP]

It's a sad fact of life that any nontrivial code will, immediately
after distribution, suddenly prove to have innumerable bugs.  Right,
another windows fix.  It affects the position at which an insertion is
done in a particular case during the screen update.  It can only happen
to unframed windows.  Here's a diff listing for corrections to
display.c.
