Fix bug when $indent have some string

assuming ```$ident = '¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨'```:
before:
```
¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨<script type="text/javascript">
¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨    //<!--
¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨    Some script here...¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
    //-->
¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨</script>
```

now:
```
¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨<script type="text/javascript">
¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨    //<!--
¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨    Some script here...
¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨    //-->
¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨</script>
```
