<p>Tests for a bug in the paragraph separator insertion code that would add an extra newline when inserting a paragraph separator at the end of a paragraph in text that preserves newlines.  Also, an extraneous space would be added after 'foo'.  Only one newline should be added.  And there should be no extraneous spaces.</p>
<p><b>It demonstrates a bug:</b> too much padding is left between the new line and the end of the paragraph containing 'foo'.</p>
<div id="test" contenteditable="true"><pre>foo
bar</pre></div>
