Greetings, I have a case in RAT where we want to append a line to the help text when the option has multiple arguments or when we have defined a default value.
I have implemented this in a renderOptions() implementation in CLI 1.8.0. In both cases we use the Option to check for some state and then append to the optBuf. I am now migrating to 1.9.0 and have to do the same thing, but 1.9.0 adds more functionality to the default renderOptions() method so I have to rework my implementation. However, had I not known this was the case, I would have missed the changes and we would have had some rather interesting bugs later. What I am proposing is a new parameter to renderOptions(). A "Optional<String> Function<Option>". If the function returns a String then it is appended to the optBuf. This method would be called near the end of renderOptions. Thoughts?
