Hi Ralf,

I've considered and rejected both, partly because in some unusual cases
I've had to create directories in directories that are also writable
by others.  Instead, I used the mkdtemp script that I recently removed
from coreutils: there, I can now rely on the mktemp binary instead.

Using mkdtemp here is almost certainly overkill here, but who knows...
