Hmmm. I'm not sure, but I suspect this may be platform-specific.
Actually, testing on Cygwin, I don't get any error at all:

$ uname -a
CYGWIN_NT-10.0 ti47 2.5.0(0.297/5/3) 2016-04-11 09:58 x86_64 Cygwin

$ false | head -1; echo $?
1

$ cat /etc/services | head -1 ; echo $?
# Copyright (c) 1993-2004 Microsoft Corp.
0

I don't know why that's the case.
