What version of Go are you using (go version)?

$ go version
go version go1.16.3 linux/amd64

Does this issue reproduce with the latest release?

Yes.

The Value example in the flag package (https://golang.org/pkg/flag/#example_Value) uses the code:

if u, err := url.Parse(s); err != nil {
	return err
} else {
	*v.URL = *u
}
return nil

golint reports:
if block ends with a return statement, so drop this else and outdent its block (move short variable declaration to its own line if necessary).

Not sure if the code should be modified.

Thanks.
