toString with only 's' or 'm' fails

[coreygeesey]

require('datejs');

var format1 = "s";
var format2 = "ss";
var format3 = "hh:mm:s"

var myDate = new Date();

console.log("One s: "+myDate.toString(format1));
console.log("Two s: "+myDate.toString(format2));
console.log("Formatted hh:mm:s: "+myDate.toString(format3));

Results are:
[coreyivr]# node myDate.js
One s: 2016-10-14T09:59:21
Two s: 21
Formatted hh:mm:s: 09:59:21

It's an easy enough fix in my code (just use ss and strip the zero if there is one), but it would be nice to get this fixed in the library.

edit:

A similar situation arises with just one m as well.

require('datejs');

var format1 = "m";
var format2 = "mm";
var format3 = "hh:m:s"

var myDate = Date.parse("October 14th, 2016 10:03 PM");

console.log("One m: "+myDate.toString(format1));
console.log("Two m: "+myDate.toString(format2));
console.log("Formatted hh:m:s: "+myDate.toString(format3));

Results:
One m: October 14
Two m: 03
Formatted hh:m:s: 10:3:0
