HTMLParser.HTMLParser and derived classes crash when
two tag attributes are glued like:

WIDTH="512"HEIGHT="83"

Example from IDLE:

>>> import HTMLParser
>>> BUGTEXT = """
<table CELLSPACING="0" CELLPADDING="0" BORDER="0"
WIDTH="100%">
<tr><td align="center">
<table CELLSPACING="0" CELLPADDING="0" BORDER="0"
WIDTH="600" BGCOLOR="white">
<tr><td WIDTH="512">
<img SRC="/pict/img83.jpg" WIDTH="512"HEIGHT="83"
BORDER="0" VSPACE="0" HSPACE="0">
</td><td WIDTH="2"></td>
</tr></table></td></tr></table>
"""
>>> parser = HTMLParser.HTMLParser()
>>> parser.feed(BUGTEXT)
>>> parser.close()
Traceback (most recent call last):
  File "<pyshell#19>", line 1, in ?
    parser.close()

Raising an exception for this seems reasonable to me.  It is not 
valid HTML or XML to my knowledge so I don't see the problem 
here.  If there still is one please enlighten me.

I agree with bcannon. Tagging as "Not a bug".
