Summary:                    head does not exit with exitcode of 1 when file not
found (mismatch with coreutils)
Description: 
head is supposed to exit with exitcode of 1 (or at least non-zero) when
there is an error.

Coreutils:
$ head ''
head: cannot open `' for reading: No such file or directory
$ echo $?
1

(proper exitcode of 1 for error)

Busybox:
$ ./busybox head ''
head: : No such file or directory
$ echo $?
0

(error message printed but still exits with 0 to signify success)
