acme: fix hiding of top windows when loading a dump file (thanks Xiao-Yong)
When loading an acme dump file that contains a window with only one
tag line, there are cases where acme hides that window (i.e. not even
its tag is visible).
The following commands reproduce the issue:
% ed <<EOE

/lib/font/bit/pelm/unicode.8.font

.

% window -dx 900 -dy 600 'acme -l /tmp/test.dump'
