I don't have any issue with this change, but the only way I see to introduce a
space into the tempfile name is to set $TMPDIR to '/path/with silly spaces' or
something simmilar. I think we discussed this before, but it would alsmot make
sense to, instead of quoting everything, instead specify -p ./ to ensure the
tempfile has no spaces.
