Sure, the link is removed, but I haven't lost the referenced file. I
must admit that I can't think of any alternative behaviour that I'd
prefer. What _should_ happen?

As I understand things, it looks like this:
ln -s /tmp/z ~/z1
make ~/z1 a symlink to /tmp/z (which doesn't exist)
mv ~/z1 /tmp/z
move the symlink ~/z1 to /tmp/z
oops, can't "dereference" ~/z1, spit a warning
And at that point, you want it to fail, rather than moving the link.
Have I got it straight?
Ciao,
Sheldon.
