argp has default behavior of using
-?/--helpfor help,-V/--versionfor version, and--usagefor short help. This is not customizable, but can be opted out of withARGP_NO_HELP. Then you need to handle these 3 flags yourself, which this PR does.Now
-h/--helpis for help,-V/--versionis for version, and--usagefor short help. I would love to remove--usageas well, but argp error messages sayTrybfcli --help' orbfcli --usage' for more information.and this is non-customizable.Wdyt? Is behaving like a "standard" CLI worth this extra code?
