Oops, I assumed BSD's utils would at least escape '\n'
but looking at their code they just output it directly.

So therefore BSD and old GNU don't support checksum files
in BSD format when any file names contain a '\n'. Fair enough.

So then , I suppose we should use the existing GNU escape mechanism
in this case too. I.E. if there is a '\n' character in the name,
then add a '\' at the start of the line and replace any
'\' with "\\" and '\n' with "\" + "n".

BTW, I'm wondering why we enable escaping on output when
there are '\' characters in the name, but no '\n' chars?
Avoiding that would increase compatibility with the BSDs.

cheers,
