I have been using a Text widget as an edit buffer for an interpreter.
When I come close to filling up the buffer, I would like to delete the
top 1/3 of the text.

I have been using XtTextReplace to replace the top 1/3 with an empty
XtTextBlock.  The deletion should not affect the currently displayed
text, but for some reason the widget decides that it needs to redraw
the screen.

Is this a bug, or am I going about things the wrong way?
