Just an update.
Attached is my current org-related file as taken off from Charles file
A small bug in Charles' file:
org-time-stamp-rounding-minutes set to 5 (rather than to 2 numbers) had me
spend a day of lisp debugging (not something I am very adept at :-).  [Why
the H___ emacs allows ill-typed customizations when the vars are
meticulously typed?? Gawd knows! ]

Another (unimportant) bug is that  org-log-done should be set to time (not
'(done))  [This is masked because the same setting is an infile setting in
Charles setup]

The rest are cleanups, regularizations and Charles->Rustom conversions

I am posting this here because I'm too dumb to have worked this out on my
own without Charles' excellent tutorial and files and others need
not spend the time I did
