David Smiley updated LUCENE-5734:
---------------------------------

    Description: 
Consider this simple input:
{noformat}
<em>hello</em>
{noformat}
to be analyzed by HTMLStripCharFilter and WhitespaceTokenizer.
You get back one token for "hello".  Good.  The start offset of this token is 
at the position of 'h' -- good.  But the end offset is surprisingly plus one to 
the adjacent </em>.  I argue that it should be plus one to the last character 
of the token (following 'o').

FYI it behaves as I expect if after hello is an XML entity such as in this 
example: {noformat}hello&nbsp;{noformat} The end offset immediately follows the 
'o'.
