And as long as I am responding I made another mistake in the above.  I
ended with C-x C-q, which will then ask you if you want to save the
result.  I should have finished the dired edit using C-c C-c instead.

I use regions with macros a lot.  I consider complex macros somewhat a
brute force solution.  But they do work and I use them a lot.

And that was another mistake in the above.  Because I was slightly
confused when I composed the macro above.  Normally in dired mode both
C-n, n, and C-p, p (dired-next-line as you found) snap to the
beginning of the file entry.  Therefore when I wrote the above that is
what I was thinking would happen.  Oops.  It's a bug in my example.
Sorry.  But at least you figured it out and were able to add an
additional emacs tool into your toolbox. :-)

Good!  I am glad you figured it out.

That is a good idea!
