Title: Call du with quoted $archdir

du wasn't receiving $archdir in a quoted form, so trees with spaces
weren't being correctly handled, resulting in USIZE being null, which
eventually resulted in

if test $leftspace -lt ; then

being placed into the run script which would of course error when it
was run.
