Could you please add tests?

Look at test_find, test_rfind and test_count methods in Lib/test/string_tests.py and add similar double loops in test_index and test_rindex.

cpython/Lib/test/string_tests.py

Line 173 in da1d468

self.checkequal( 2, 'rrarrrrrrrrra', 'find', 'a')

cpython/Lib/test/string_tests.py

Line 177 in da1d468

self.checkequal( 2, 'rrarrrrrrrrra', 'find', 'a', None, 6)

are the leading whitespaces just before 2 kept for readability??
