bug#45019: 28.0.50; Odd "grep -n" behaviour

[Lars Ingebrigtsen]

emacs -Q
M-: (grep "grep -n emacs configure") RET

Everything works fine:

Repeat:

M-: (grep "grep -n emacs configure") RET

Things do not work now:

Because the second time around it did not add "/dev/null" at the end
there.

Adding a -H would have fixed this, but calling the same function twice
should either fail both times, or work both times.
