OK, so if I understand correctly, I can use the fixes you described  
and either use 4.1.5, or wait until the next release (or the next pre- 
release build that contains it)?  The behavior I currently see in 4.2  
and 4.2.1.5-svn9aug2009 (which I'm assuming doesn't have today's  
fixes) is that nothing happens on copy.

In any case, thanks for your helpful response!  I'll likely post here  
about the working code sometime soon, in case it's of interest to the  
community.

Best,
