Test for :first-letter punctuation extension

Attached are two files that I'm contributing to the CSS 2.1 test
suite.  The story behind them is a little complicated, though.

In the tests that Microsoft contributed, there are 412 tests, named
first-letter-punctuation-001.xht through
first-letter-punctuation-412.xht , which are extremely repetitive.
I don't think it's appropriate to have such repetitive tests in a
manual test suite, because of the costs in time of both reviewing
and running them.

This test is an attempt to put all of those tests in a single file
that can be easily verified at a quick glance.  Furthermore, this
test also attempts to test the negative:  that any characters not in
the punctuation classes given do not cause extension of the string
covered by the :first-letter pseudo-element.

This means the resulting test is extremely large, and loads very
slowly.  It's also failing, for a few characters, in all the
browsers I've tried it in.  I haven't yet analyzed if that's a bug
in the test (e.g., making assumptions that it can't make about
certain whitespace characters) or a bug in the browsers in question,
though I suspect it's a bug in the test.

However, I wanted to get the test contributed before the September
15 deadline even though it's incomplete.  So, attached are:

 1) an HTML file that is the beginning of the test
 2) a python script to generate the large part of the test file (the
    hardcoded path in it should be changed to the location of the
    appropriate file from the Unicode 5.1.0 character database),
    which should replace the last 6 lines of (1)
