Log Message:
Backport checkin:
Fix a bug in the memory reallocation code of PyUnicode_TranslateCharmap().
charmaptranslate_makespace() allocates more memory than required for the
next replacement but didn't remember that fact, so memory size was growing
exponentially every time a replacement string is longer that one character.
This fixes SF bug #828737.
