It's not quite so simple.  "find -print0" and "xargs -print0", its
counterpart, let people deal with pathnames that contain spaces
as well as newlines.  That's not a problem for "comm" or its
friends.

For the most part, text tools are based around newline delimitation.
There is no particular reason AFAIU to single out 'comm' here.  If
you want to retrofit zero-delimited records into all the coreutils
(and 'awk' and many others too) that's a different matter.
