Thanks, @rauhul! Do you mind dropping the whitespace changes? I'd rather not introduce conflicts with other things that are in flight. |

@natecook1000 yep I can drop the whitespace changes! |

Hmmm, other than moving short names to the beginning, the old version preserved the declaration order of the names, which seems important for at least some cases. What’s motivating this change in behavior?

that's a fair point, I thought it made more sense to put the arguments in order, but you're right, using declaration order allows the user to move depreciated flags to the back of the help, I'll back out this change.

- Removes unused codepaths. - Simplifies synopsis string codepaths by removing optionality. This complexity is moved to the caller who is now responsible for filtering out hidden arguments and options. This change is desirable as it allows the caller to determine if the argument should be hidden. For example, while it makes sense to hide arguments in help text, it may not make sense to hide them when dumping the arguments for another tool to consume.
