Fix a byte compiler bug with characters above ?\xFF. lisp/ChangeLog addition: 2009-02-22 Aidan Kehoe <kehoea@parhasard.net> * bytecomp.el (byte-compile-force-escape-quoted): New variable, used to force `byte-compile-insert-header' to treat the output as having characters above ?\xFF. (byte-compile-from-buffer): If the compiled output contains characters above ?\xFF, and byte-compile-dynamic-docstrings or byte-compile-dynamic is non-nil (or we're using an inappropriate coding system) recompile the file, turning off the dynamic features and using a more appropriate header. (byte-compile-insert-header): Pay attention to byte-compile-force-escape-quoted. tests/ChangeLog addition: 2009-02-22 Aidan Kehoe <kehoea@parhasard.net> * automated/mule-tests.el: Use more realistic tests for the escape-quoted mule encoding checks; update a comment, change a Known-Bug-Expect-Failure to a normal test now that we've addressed an old bug.
