This can be called with NULL from the code below (if the option is last
on in argv with no argument after it).

You need to check if argv[i][len + 2] == 0, if not then the option did
not match.

If this returns false then it should continue parsing the next letter as
another single-letter option.

I think you should also make '=' work (ie "-x=12").
