Comment(by jstolarek):

 Except for what Edward pointed out, another reason why I decided to filter
 out short flags is that almost all of them require additional parameter
 (e.g. -H1G), which cannot be auto-completed. If you think that `filter` is
 unnecessary than of course it can be removed. I'm also not sure if
 removing `filter` will not cause any glitches - I think that some of the
 short options might have been duplicated on the list, but I'm not sure of
 that. I can provide new patch tomorrow - at the moment I'm getting some
 unexpected compilation errors.
