help: still print 0-length argument descriptions

Browse Source 
I think I had initially intended 0-length descriptions to be "hidden"
options, but this doesn't really work well with arguments, and it also
doesn't make intention clear. Perhaps an additional field should be
added to the parameter specification to support hiding options
(this does not make sense for non-named options).
