It's certainly *possible* to write such code: just catch
the error and continue.

This is a more serious matter, but it's a judgment call as to
whether it stopped working or started working.  Some users
want permissions to be saved, as well as contents.  Others
don't.  Emacs should support both usages.

I'm still puzzled as to why you're observing the problem and
I am not.  Can you do an 'strace' on an Emacs that's exhibiting
the problem?  It'd be helpful to see exactly which system calls
are being invoked, and the errno value for the failing one.
Possibly there is a small workaround here that wouldn't require
redesining copy-file.
