Update.
* posix/regcomp.c (build_word_op): Rename like... (build_charclass_op): ...this. Accept two extra parameters, CLASS_NAME and EXTRA. Add EXTRA to the result, not only _. (peek_token): accept \s and \S as OP_SPACE and OP_NOTSPACE. (parse_expression): replace build_word_op with build_charclass_op, add new arguments, accept OP_SPACE and OP_NOTSPACE. * posix/regex_internal.h (re_token_type_t): Add OP_SPACE and OP_NOTSPACE.
