Sorry, but I do not see much benefit to this feature.
It would be harmful to the common case of 'comm' being piped into
another program. It would also be confusing in some cases, e.g., the
following example:
$ for c in a b; do echo "Only in $c" > $c; done
$ comm a b
Only in a
Only in b

Some people dislike extra text in 'wc' [1]. Sadly, we can not make
everyone happy.
