Subject: [PATCH] fix color of erased characters

This was responsible for eg: dialog rendering a black (or whatever
the default background color was) strip behind the text in an
invocation like:

`dialog --yesno hello 0 0`

Rather than render a default cell, render a blank cell using the
current pen.
