Easily replace only the messages for --help and --version

[porglezomp]

I'm trying to help make a project's help messages consistent, and all of the messages are of the format "Start …", "Check …", "Print …", so the "Prints version information" stands out. I was unable to find an easy way to replace only the help and version messages without re-wiring the commands themselves. Is there any easy solution I missed, or is this something that would have to be added.

There isn't a way to do this currently. You can override the --version by supplying a flag with the long of version. The only downside to doing this, is you'll need to check if it was used and print the version/exit accordingly. But that's only about 3 lines of code, so in practice it's not too bad.

Would you appreciate a contribution that adds this? It's obviously easily worked around, but seems like it would be nice to have for other people as well.

I would be willing to consider it, sure! I don't have the bandwidth to work on it right now, but would gladly look at a PR adding it.

So I'm working on this, and am wondering what you think the methods should be called. On args it's help, but with the help arg that gets awkward. Do you prefer help_message and version_message, help_help and version_help, or something else?

Also, where in the yaml should these customizations end up? Based on the help_short and version_short it looks like they should top level?
