What have I done now ? (aka CR and LF confusion)

[Brian Milby]

You need to use binfile on Mac to get sane line endings.  I have a PR to fix, but doubt it will get merged.

On Mac/Windows, file will convert line endings to what LC thinks is the native one for the OS.  CRLF for Windows and CR for Mac (the real CR, not the one that LC uses internally where CR and LF are synonyms for LF).  So on Linux you can use either file or binfile, on Windows you need to use file, and on Mac you need to use binfile to get the currently expected line endings.

Thanks,
Brian
