Add aliases like "/?" or "-?" to built-in "--help" verb

[ayeltsov]

I'd like to add couple of commonly used aliases like "/?" and "-?" to the built-in "--help" verb.
Is this possible?

Didn't find that in documentation or existing issues.

Thanks!

#686 is a PR to add the commonly-used -h alias for --help, and -V for --version. Note that in the Unix getopt world, which this library is designed to mimic, /? and -? are not commonly-used aliases, which is why I wrote that PR to hardcode the -h and -V aliases rather than allowing them to vary. If this library ever implements a "Windows parser mode" where / is the default option designator character instead of -, then /? would make sense. Meanwhile, if you want to look at the poll at #686 (comment) and vote, please do. Currently it's 4 in favor of hardcoded -h and -V alias, and 1 against, so I'm currently inclined to leave that PR as-is. Please leave a comment over there arguing for reasons not to do that, if you want.
