Regarding portability, the reference I use is IEEE Std 1003.1, 2004 Edition,
http://www.opengroup.org/onlinepubs/009695399/

Unfortunately this is only a guide -- for example /bin/sh on SunOS 5.8
doesn't support "export x=y", even though it's mandated by the reference
above.  (Of course, SunOS 5.8 came out before 2004.)

sed -i is a GNUism, that is, it requires GNU sed.

I usually use -r, not -R, but I'm not aware of the portability
implications of either.  That is, I find -r easier to understand.

In this case, I don't think the changed behavior (loss of
--preserve=mode,ownership,timestamps,links and --no-dereference) will
cause problems.
