Why there's no return in SelectStmt.Restore

[loxp]

Question

func (n *SelectStmt) Restore(ctx *RestoreCtx) error {
        ......
	if n.TableHints != nil && len(n.TableHints) != 0 {
		ctx.WritePlain("/*+ ")
		for i, tableHint := range n.TableHints {
			if err := tableHint.Restore(ctx); err != nil {
				errors.Annotatef(err, "An error occurred while restore SelectStmt.TableHints[%d]", i)
			}
		}
		ctx.WritePlain("*/ ")
	}
        ......
}

Why not return errors.Annotatef()? If error occurs, the error will disappear and cannot be found in return value.

This looks like a typo. Would you mind filing a PR fixing this? Thanks!
