Yeah, I know.  As a developer, I am acutely sensitive to both sides of the
issue.  The result:  never change things unless there's a real reason,
and when there is a real reason, leave around some bread crumbs
so nobody has to go Googling to figure things out.  Here, the new code
just quietly ignores the numeric prefix (a technique I've been using for
30 years now).  It left me grumpy.  :)  Thank you.  I will now retrain
my fingers to prefix this particular command with Ctl-u.  Ick.  :(
"non-numeric prefix" is a new feature that must have cropped up in the
last 20 years.  :-D

I know the stuff is always documented somewhere.  The problem is
finding it.  Thank you again.  Regards, Bruce
