I don't see it in my rcs logs, but I seem to recall that "cp -p" would
copy timestamps but not protection modes on Apollo SR9.something.

tar works too... (but I've found it generally more useful to copy symlinks
as symlinks than the targets).

actually I'm well aware of the distinction. I use my own copy utility,
which I wrote back when I first encountered "cp -r" on a BSD system
in the 80's. (It had an unfortunate habit of dumping core, and wasn't
implemented on Apollo anyway).
