[Mark Favas, on new test_sre failures]

Checkins are never supposed to leave the test suite in a failing state, but
while that's "the rule" it's still too rarely the reality (although *much*
better than it was just a month ago -- whining works <wink>).  Offhand these
look like shallow new failures to me, related to /F's so-far partial
implemention of PEP 223 (Change the Meaning of \x Escapes).  I'll dig into a
little more.  Rest assured it will get fixed before the 2.0b1 release!
