Copying through a destination symlink is fundamentally risky,
so I've changed cp not to do it anymore.
Here's where I announced this change (there's been no feedback):
http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/11922
a little more background:
http://bugzilla.redhat.com/243588
Best is just not to do that anymore. However, if it's something
you cannot easily avoid, you can do this instead:
$ cp -p link1 $(readlink -f link2)
