Enhancement: Need a global --help (-h) flag to show the help information shown when the 'help` command is selected

[kcq]

Right now running mint -h or mint --help prints this error: Incorrect Usage: flag: help requested. We need to handle these use cases properly. For that we need to define an extra global flag to handle --help (with -h as an alias) and print the same info when mint help is typed. This would be similar to what happens with the global --version flag.

Hey @kcq now when I run mint -h or mint --help I get the same result as mint help but it gives incorrect flag. so we need to define an extra global flag to handle --help with -h as an alias. If it good to go then I am taking this issue.

I think the file to handle this is vendor/github.com/spf13/pflag/flag.go

The spf13/pflag library is an indirect dependency and it's not used by the app itself. The CLI commands and flags are handled with the urfave/cli library.

Feel free to work on the enhancement. If you have any questions add them here.
