[jira] Commented: (CLI-124) HelpFormatter should be more cunning when deciding if a Group is Optional and therefore square-bracketing it

["Oliver Heger (JIRA)" <ji...@apache.org>]

Oliver Heger commented on CLI-124:
----------------------------------

If I understand this correctly, we need a notion for: This child group is optional, but if it is present, it must have at least n elements, correct?

> Currently all child groups are required to satisfy their constraints (defaul is any thing goes) and so if you have a Group A as a child of Group B and set a minimum of 1 on A then B is no longer Optional as A is not Optional.
