Allow no indentation in strings.Indent

When recursively generating YAML, it is useful to have a simple generic template definition that starts with an indent of 0 and increments at each level YAML.  If you pass `width` of 0 to the function as it was before this change, it would indent it one level without complaining, which was a great source of confusion to me.
