since you already use two GNU-specific features (-r and -0 in xargs), you
could as well adopt another one:

    find . -name '*.c' -print0 | xargs -r0 grep -H include
or
    find . -name '*.c' -print0 | xargs -r0 grep --with-filename include

The solution with /dev/null is a kludge.

(OTOH, I admit that it was unfortunate to advice ``grep -r --include''
because the user learns more from the find pipeline.)
