`gopass create` wizard template `min` & `max` attributes are not enforced

[chaorace]

Summary

The min & max options for the wizard attributes of gopass create appear to be unimplemented and seem to have no effect.

gopass/internal/create/wizard.go

Lines 35 to 42 in 16c071a

	type Attribute struct {
	Name string `yaml:"name"`
	Type string `yaml:"type"`
	Prompt string `yaml:"prompt"`
	Charset string `yaml:"charset"`
	Min int `yaml:"min"`
	Max int `yaml:"max"`
	}

Steps To Reproduce

1. Invoke gopass create
2. Select the stock "PIN Code (numerical)" template when prompted
3. When prompted for "Authority (Issuer)" press enter without providing any input
4. Observe that the template attribute's minimum length requirement was not respected

gopass/internal/create/wizard.go

Lines 99 to 106 in 16c071a

	Welcome: "🔑 Creating PIN Code",
	Attributes: []Attribute{
	{
	Name: "authority",
	Type: "string",
	Prompt: "Authority (Issuer)",
	Min: 1,
	},

Expected behavior

Because the authority attribute specifies a minimum length of 1, the wizard should immediately abort when given an input value that is too short (and vice versa for the max attribute).

The ergonomics and implementation should essentially be the same as the current wizard behavior for when a hostname cannot be extracted on an attribute of the hostname type

gopass/internal/create/wizard.go

Lines 234 to 237 in 16c071a

	hostname = extractHostname(sv)
	if hostname == "" {
	return fmt.Errorf("can not parse URL %s", sv)
	}
