Fixes #2817. This is now more consistent with Homebrew's
list
, though not completely, because Homebrew'slist
refuses to give any output when there is an invalid Formula
argument. Our
list
stumbles forward instead, giving suchoutput as is possible based on valid args, but still exiting
with error when invalid args are seen.
