This has been bounced around for a couple years now #474 and a few others have expressed desire to work with non-standard option names. We have been somewhat resistant to that but I think it can be done now. This PR adds a modifier `allow_non_standard_option_names()` It is purposely long, it is purposely off by default. But what it does is allow option names with a single `-` to act like a short option name. With this modifier enabled no single letter short option names are allowed to start with the same letter as a non-standard names. For example `-s` and `-single` would not be allowed. --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: Henry Schreiner <HenrySchreinerIII@gmail.com>
