Unique values in flags where repeatable is true

[auryark]

I think it would be nice if flags with repeatable: true only took unique values. I've been doing this kind of filtering using bash's built-in regex operator, so I did a test by manually editing a generated script and adding it to the parse_requirements function of a command:

if [[ -z ${args['--image']+x} ]]; then
  args['--image']="\"$2\""
else
  if [[ ! "${args['--image']}" =~ $2 ]]; then
    args['--image']="${args[--image]} \"$2\""
  fi
fi

Maybe that would be a possible solution.

It is a good idea but:

1. The regex might also filter out similar values.
2. Shouldn't setting repeatable to also be unique be something that the developer should choose explicitly? I mean, perhaps there are occasions where non-unique are desired?

I have implemented #454 and #456 to add support for unique: true for flags (only when they have repeatable and arg) and for args (only when they are repeatable).

Thanks for implementing my suggestion. I didn't have time to come here and thank you. This feature has been so much useful for me.

Sure thing, you have good ideas :)
