Follow-up Comment #1, bug #39706 (project grep):
Not a bug; this behavior is required by POSIX. That's why you'll often find
recipes such as:
xargs grep $pattern /dev/null
which combines /dev/null (which will never match) along with your list
(possible one file long) from xargs, so that grep sees at least two files, and
starts listing file names.
