Character class escapes (``\d``, ``\D``, ``\s``, ``\S``, ``\w`` and ``\W``) that occur outside a character set are now compiled directly to a single CATEGORY opcode instead of being wrapped in an IN block. This removes the IN wrapper (three code words) and an indirect charset() call, and makes such an escape a simple repeatable unit so that, for example, ``\d+`` uses the REPEAT_ONE fast path; a CATEGORY case is added to SRE(count). The transformation preserves behaviour exactly. For category-heavy patterns the compiled byte code is about 20% smaller and matching is up to ~2x faster, with no effect on patterns that do not use bare category escapes.
