Hi there,

Just sending the bug to the mail list in case it got lost in the bug 
tracker.

Cut utility incorrectly replaces null-byte (0x00) with \n (0x0a).

Tested with Busybox 1.36.0 and Busybox 1.20.0 ("Busybox in VM" link on 
the website).

Busybox:
$ echo -ne "\x00\x01\x02\x03\x04\x05\x06" | ./busybox cut -b 1-3 | 
hexdump -C
00000000  0a 01 02 03 0a                                    |.....|
00000005

GNU coreutils:
$ echo -ne "\x00\x01\x02\x03\x04\x05\x06" | cut -b 1-3 | hexdump -C
00000000  00 01 02 0a                                       |....|
00000004
