Add support for long help or additional 'help' flags, or both.

[henvic]

I want to add a --long-help flag (with -H shortcut) that will show a longer help.
This could easily be done with support for marking additional help flags or by letting the user choose a set of flags and shorthands to use for help.

I'd have to parse the flags separately and set the help flag programmatically whenever I find a -H or --long-help flag. I have tried to work around this with a 'persistent run' structure but it is just too much code and doesn't work when PositionalArgs that requires a minimum number of arguments is in use.

See:

cobra/command.go

Lines 694 to 696 in 4dab30c

	// If help is called, regardless of other flags, return we want help.
	// Also say we need help if the command isn't runnable.
	helpVal, err := c.Flags().GetBool("help")

I have also noticed that auto generated doc doesn't contain long description of Long field of a cmd struct.

There wasn't much traction on this issue and its quite old. Going to close as part of #1600 but if this is still something you struggle with feel free to reopen.

If I understand you correctly, you just want the ability to mark other flags so they have the same high priority as the existing --help which will short circuit other logic. If its not still an issue, disregard my question.
