use of [repeat][/repeat]

If i use [repeat][/repeat] like this

<table>
[repeat]
<tr><td>[node:title]</td></tr>
[/repeat]
</table>

in the mail the html rendered will be

<table>
<tr><td>lorem</td></tr><br />
<tr><td>lorem</td></tr><br />
<tr><td>lorem</td></tr><br />
...
</table>

<br/> shouldn't have been there

In newsletter.module on line 752
I change
$body = implode('<br/>', $items);
by
$body = implode('', $items);
