In the generated manpage, the indentation of a command following a command with only hidden options is wrong.

[chipaca]

If for some reason you have a command that has options, but all the options are hidden, then the command that appears after it in the manpage will be indented beyond where it should be.

As an example, given

package main

import "os"
import "github.com/jessevdk/go-flags"

type options struct {
	A struct {
		Hidden bool `long:"hidden" hidden:"yes"`
	} `command:"a" description:"the a command as one hidden option"`
	Z struct{} `command:"z" description:"the z command gets indented wrong :-("`
}

func main() { flags.NewParser(&options{}, 0).WriteManPage(os.Stdout) }

as /tmp/bug.go, then running go run /tmp/bug.go | MANWIDTH=60 man -l - gives you
