That is ok, though it would be better if there were some
standardized representation of "<unknown>".  I think either
"" or #f would be reasonable.

I would read the question:
     Does `command-line' include the equivalent of argv[0]
as:
     is the first element (car) of command-line argv[0] or argv[1]
and we *really* don't want that to be unspecified.
