Fix: ESC[E and ESC[F with no arguments did not move the cursor on the legacy terminal of Microsoft Windows

[hymkor]

The default value when arguments are omitted, was not set as 1.

This behaviour was not reproduced on the new Windows Terminal. I do not know the reason.

If no problems, could you please merge my patch ?

ESC_F.go

//go:build run

package main

import (
	"fmt"

	"github.com/mattn/go-colorable"
)

func main() {
	o := colorable.NewColorableStdout()

	fmt.Fprint(o, "First line\n")
	fmt.Fprint(o, "\x1B[FSecond line\n")
}

ESC_E.go

//go:build run

package main

import (
	"fmt"

	"github.com/mattn/go-colorable"
)

func main() {
	o := colorable.NewColorableStdout()

	fmt.Fprint(o, "First line\n")
	fmt.Fprint(o, "\x1B[ESecond line\n")
}
