Log Message:
-----------
Correct what is considered punctuation for ::first-letter
https://bugs.webkit.org/show_bug.cgi?id=315100
Reviewed by Antti Koivisto.
Aligns us with the specification and Gecko.
Chromium gets a number of cases from our internal test (that I modified
and turned into a WPT) wrong. It mostly fails to find the first letter
or fails to include some punctuation.
I created a separate tentative test for C0 code points as the
specification is not entirely clear.
