Comment(by golubovsky):
Well, the idea of newline-separated names was that output is immediately
printable, and can be tirned into a list of strings using the lines
function.
Zero-separated output does not have this property.
OTOH, there was an alternative proposal in my e-mail that the handle could
provide a serialized list of {{{FileStatus}}} (or similar) structures,
which is slower of course, but if one wants to extract as much file
information as possible not worrying about being printable this is IMHO a
better (yet complicated) way.
I still stand for newline-separated output.
