Parse behaviour is wrong when flag contains "-"

[ty2]

ENV

export NODASH=1
export HAVE_DASH=2

Config file

nodash=10
havedash=20

var noDash string
var haveDash string
flag.StringVar(&noDash, "nodash", "0", "noDash")
flag.StringVar(&haveDash, "have-dash", "0", "haveDash")
flag.Parse()
fmt.Println(nodash, haveDash) // "10" "2",  expected result should be "10" "20"

mistake, sorry
