+Fixed a regression where raw f-strings incorrectly interpreted escape
+sequences in format specifications. Raw f-strings now properly preserve
+literal backslashes in format specs, matching the behavior from Python 3.11.
+For example, ``rf"{obj:\xFF}"`` now correctly produces ``'\\xFF'`` instead
+of ``'ÿ'``. Patch by Pablo Galindo.
