Very good.  In fact: Excellent!

Thank you for a wonderful piece of code (the :listfile part) and,
even more importantly, for the great documentation ("explanation").

I would particularly like to compliment you on your wise use of
"PRIV" (a very smart -- preventive -- way of avoiding the common
misspelling of "privileged" as "priviledged").

Your note is accurate and precise.  It made my day.
