* replace unicode categories with raw list of code points * simplifying ranges * fixing variable length quotes * removing redundant regular expression * small cleanup of regexp notations * quotes and alpha as ranges instead of alterations * removed most regexp dependencies and features * exponential backtracking - unit tests * rewrote expression with pathological backtracking * disabling double hyphen tests for now * test additional variants of repeating punctuation * remove regex and redundant backslashes from load_reddit script * small typo fixes * disable double punctuation test for russian * clean up old comments * format block code * final cleanup * naming consistency * french strings as unicode for python 2 support * french regular expression case insensitive
