Hi
I think thats a really bad idea. We want options that work and do the sensible thing. When would a user want to set these options to different values? Without a use case, and a potential user, these extra variants are a waste of hard-drive space.
I thought the use case I had in mind was apparent from the context: finding out the terminal width and then setting the wrap-width accordingly. And the max. description indentation could be set as a percentage of the terminal width. This is all quite similar to what pretty printing libs allow.
I'd suggest a much better idea would be to have one function which did all this, in the IO Monad. Some sort of showTheGetOptHelpWithTheRightWidth :: IO (). Before adding a function I think its important to ask "what will this function be used for" - if there are no particularly good answers, then its best not to add it. If it happens to be a general case of something where everyone will want a specific case then the specific case seems more appealing.
Generally I think that hard-coding numerical constants in code is nearly always a very bad idea.
Agreed :-) Thanks Neil
