Summary: htmllib broken 

Initial Comment:
Responding to a question in python-help about extracting links from web pages, I wrote a simple href printer (see attached file). When run using 2.2a4, it never prints anything.  It outputs a list of hrefs when run with 2.1 or 1.6.  Either there's a bug somewhere (in my code possibly, though it's pretty simple) or some semantics changed that I
missed.

I thought maybe the method resolution order change affected things, but htmllib.HTMLParser only uses single inheritance.  When displaying help about
htmllib.HTMLParser, pydoc.help does emit the method resolution order, which it doesn't generally seem to do:

    class HTMLParser(sgmllib.SGMLParser)
     |  Method resolution order:
     |      HTMLParser
     |      sgmllib.SGMLParser
     |      markupbase.ParserBase
     ...

Please attach the input for which this fails.  A trivial
test case does not fail (see Lib/test/test_htmllib.py).

Set status to "pending".

SF apparently doesn't like file uploads from Opera, so it's pasted here...

import htmllib, formatter

class MyParser(htmllib.HTMLParser):
    def anchor_bgn(self, href, name, type):
        print href

fmt = formatter.NullFormatter()
parser = MyParser(fmt, verbose=1)
parser.feed(open("tour01.html").read())
parser.close()
