Thanks, that saves time. I have been also checking how libc behaves,
debugging more information with optind, argv, optarg, opterr and
optopt with the short and long cases.

One side note: optopt still remains inconsistent compared to our port
version. Not sure if this is worth caring about.. Mentioning
in passing.

Adjusted on HEAD.
