In reviewing CLIs for #4132, I found some were providing helps on `-h` vs `--help` and figured that could be built directly into clap. I had considered not making this hint automatic but I figured the overhead of checking if long exists wouldn't be too bad. The code exists (no binary size increase) and just a simple iteration is probably not too slow compared to everything else. Fixes #1015
