Thanks for reporting that.
I think I have found a way to make GNU mv fail in that case --
with minimal performance impact.

cp should at least warn, too, in case someone does `cp some... files... dir'
and then upon successful completion runs `rm -rf some... files...'.

BTW, if you use mv's --backup=numbered option when running
that command, you wouldn't lose any data.
