Progress additional text at speed section incorrect work

[dmitryk-dk]

Hi! We have an issue regarding adding additional symbol if width of the text lower that it was before.
For example:
I have next template

const pbTpl = `{{ (cycle . "←" "↖" "↑" "↗" "→" "↘" "↓" "↙" ) }} {{speed . "%s samples/s"}}`

This template is used in the next code:

pbPrefix := fmt.Sprintf(`{{ green "VM worker %d:" }}`, i)
bar = barpool.AddWithTemplate(pbPrefix+pbTpl, 0)

where

// AddWithTemplate adds bar with the given template
// to the global pool
func AddWithTemplate(format string, total int) *pb.ProgressBar {
	tpl := getTemplate(format)
	bar := pb.ProgressBarTemplate(tpl).New(total)
	Add(bar)
	return bar
}

When I start the tool it shows the correct text like

VM worker 0: → 3233 samples/s

but when when the number of characters decreases, then an additional character appears at the end of the line

VM worker 0: → 323 samples/ss

VM worker 0: → 32 samples/sss

Is it possible to fix this behavior?

Hi!
It looks like it does not redraw the whole line, so I think I'll fix it
