Don Hinton c242be40a1 [CommandLine] Change help output to prefix long options with -- instead of -. NFC . Part 3 of 5 ...

Summary:
By default, `parseCommandLineOptions()` will accept either a
`-` or `--` prefix for long options -- options with names longer than
a single character.

While this change does not affect behavior, it will be helpful with a
subsequent change that requires long options use the `--` prefix.
