Empty string does not validate as stringlength in the new version

[elvinchan]

Hi everyone: A struct defined like this:

type Input struct {
	Keyword string `valid:"stringlength(3|64)"`
}

What I expect is:

Keyword == "" --> valid
Keyword == "e" --> invalid
Keyword == "eee" --> valid

It is worked in the version v0.0.0-20190424111038-f61b66f89f4a But after updated to version v0.0.0-20200108200545-475eaeb16496, the empty string does not validate

Keyword == "" --> invalid

I found it was the break change due to switch from isEmptyValue to isFieldSet

So I want to know, is the design of stringlength has changed ? Or just a bug ? If the design has changed, how do I implement the requirement "empty or specified length scope of string" ?

Thanks a lot for any help !
