Hi Marc,

good catch, an other case of getopt with GNU extensions.  Should now be
fixed.

In GNU getopt the optional argument must immediately follow the option
letter, i.e., "-12" is interpreted as option "-1" with optarg "2", but
"-1 file" is interpreted as option "-1" without optarg and "file" is the
next parameter.  It seems NetBSD getopt interprets "1::" in optstring as if
it were "1:", i.e., assumes that "-1" requires a mandatory argument.
