patch to add "-R" to touch(1)

I'm not quite sure how you deal with "non-standard" additions to standard
commands, so please be gentle!

Incidentally, I have no preference for actual implementation, this is just what
I've been using for a while. Comments welcome!

Basically, touch(1) has:

-h      If the file is a symbolic link, change the times of the link itself
rather than the file that the link points to.

and:

 -r      Use the access and modifications times from the specified file instead
of the current time of day.

If "-r" points to a link, the link is always followed to retrieve the datetime
information.

I have a program that needs to "-r" the datetime of the link itself if the file
is a link.

Up to now, I've been doing a stat of the file, and then forming the date to
add, but recently thought to add this option:

-R      As -r , but if the file is a symbolic link, return the times of the
link itself rather than the file that the link points to.

Patch attached. Comments?
