On line 66 it looks like some elements in `arguments` are not expected to be
options (they won't start with '-'). So why should all arguments be added to
options here? Are the non-option elements added to `options` but henceforth
ignored?

[Johnni Winther, 2016/04/12 12:38:36]

Done.

+  if (arguments.contains(Flags.verbose)) {

[eernst, 2016/04/12 12:10:47]

I assume the intention is to disable the '-v' form, or is there a step where
'-v' is detected and replaced/supplemented by '--verbose'?

[Johnni Winther, 2016/04/12 12:38:36]

Dooh. Removed the wrong subexpression....

     options.add(Flags.verbose);

[eernst, 2016/04/12 12:10:47]

If `arguments.contains(Flags.verbose)`, wouldn't `addAll(arguments)` already
have added `Flags.verbose` to `options`?

[Johnni Winther, 2016/04/12 12:38:36]

Dooh ... continued.
