Indeed it works.  Thanks.  I noticed that column number
is updated for all cursor movements.

Is there any way to move the (force-mode-line-update) 
up the "things to do list" for every keystroke???

The reason I'm asking is that the *line number* is updated
immediately after it changes, but, column number is noticeably
slower to update...... there is a noticeable fraction of
a second between cursor movement and column number updating.
