[pypy-issue] [issue1127] [cpyext] PyUnicode_Tailmatch() misinterprets direction flag

[Stefan Behnel]

New submission from Stefan Behnel <stefan_ml at behnel.de>:

The (not very straight forward) interpretation of the "direction" flag in
PyUnicode_Tailmatch() is that -1 denotes a prefix match and 1 a suffix match.
cpyext currently does it the other way round.

http://docs.python.org/c-api/unicode.html#PyUnicode_Tailmatch

Untested patch (also for the test cases) is attached.
