Yeah, it's just a deficiency in GNU mv. POSIX.2 says that mv should
basically do "cp -R" and remove the source files. POSIX requires mv
to move whole directory trees across filesystems, not just symlinks!
To do that, I want to make the guts of GNU cp into a module that both
cp and mv can call. But that's a nontrivial amount of work that's
never gotten important enough for me to do.
