Scott McMurray ba1a33e105 Prefer -1 for None ...

Currently we pick "weird" numbers like `1114112` for `None::<char>`.  While that's not *wrong*, it's kinda *unnatural* -- a human wouldn't make that choice.

This PR instead picks `-1` for thinge like `None::<char>` -- like clang's `WEOF` -- and `None::<bool>` and such.

Any enums with more than one niched value (so not `Result` nor `Option`) remain as they were before.
