I think it would be better to fold missing tests in from test_sre to
test_re, not so much because I've partly converted test_re to use unittest,
but because "re" is what people generally import.  It never even occurred to
me to look for "test_sre" when I was looking for a candidate test suite to
convert to unittest.  I'll keep working at completing the conversion.
