13.0-CURRENT oddity in output of dialog(1)

[David Boyd]

In 13.0-CURRENT, dialog(1) fills lines shorter than the box width with 
something other than the background color.  In an xterm session, the
fill is white. In a console session, the fill is black.

This appears to be a regression in the dialog(1) utility not seen in
previous (11.2-RELEASE and 12.0-RELEASE) releases.

To recreate:

cat /etc/rc.conf | dialog --programbox 23 76

No other problems have been observed in the dialog(1) utility.

Thanks.

David Boyd.
