Either there's an extra argv member that is always present and we want
to remove, or there's the possibility that the command-line is empty.
AFAICS we can't have both problems.

argv[0] corresponds to the filename, right?  In that case, it's not possible
to run multiboot without argv[0] (or at least, we shouldn't allow it).  Then
we can remove it unconditionally.
