Fix what looks like a copy-paste-o that originated in the same script:
command=foo >/dev/null 2>&1
This is clearly what should have been done, for several reasons.
No PORTREVISION bump because the old version simply ignored everything
after the space, and does not seem to have done any harm. However
it's good to clean these up so that similar errors aren't pasted into
a new script where they might actually matter.
