Comment 132 for bug 19250

Just want to express agreement with Brian about the desired behavior:

<span title="yes&#10;no">test</span>

+---+
|yes|
|no |
+---+

<span title="yes
no">test</span>

+------+
|yes no|
+------+

In addition - &#13; &#10; and &#13;&#10; should all produce only one line break,
and hard character sequences 13, 10, and 13-10 should all produce only one space.
(This is to handle the \r and \r\n newline conventions used by older MAC and DOS
respectively.)
