Prevent over-eager rx character range condensation
`rx' incorrectly considers character ranges between ASCII and raw bytes to cover all codes in-between, which includes all non-ASCII Unicode chars. This causes (any "\000-\377" ?Å) to be simplified to (any "\000-\377"), which is not at all the same thing: [\000-\377] really means [\000-\177\200-\377] (Bug#34492). * lisp/emacs-lisp/rx.el (rx-any-condense-range): Split ranges going from ASCII to raw bytes. * test/lisp/emacs-lisp/rx-tests.el (rx-char-any-raw-byte): Add test case. * etc/NEWS: Mention the overall change (Bug#33205).
