Hmph, while that is a good data point to explain why this one fails,
it is a very unsatisfactory workaround, compared to a world where we
do not have to worry about such a broken mv (perhaps by noticing a
broken macOS /bin/mv and automatically doing mv () { mv -f "$@" }
for them).

I am curious what other differences Torsten will find out between
good macs and bad ones.  Perhaps we can narrow down the bad apples?
