Emacs now detects a file that contains NULL bytes as binary
file and use `no-conversion' for reading that file (see the
docstring of the variable `inhibit-null-byte-detection').
And SqueakV1-18.sources cotains NULL bytes at line 26527.
When I delete that line, the file is correctly detected as
Mac-eol format.
