[Bug 1621226] Re: grep does not output null when -o is used

[Jarno Suni]

** Description changed:

  testcase
  
- $ printf 'a\0b\0b1' | grep --null-data --null b | hexdump -C
+ $ printf 'a\0b\0b1' | grep --null-data b | hexdump -C
  00000000  62 00 62 31 00                                    |b.b1.|
  00000005
  
  but
  
- $ printf 'a\0b\0b1' | grep -o --null-data --null b | hexdump -C
+ $ printf 'a\0b\0b1' | grep -o --null-data b | hexdump -C
  00000000  62 0a 62 0a                                       |b.b.|
  00000004
  
  This is fixed in Xenial, but IMO should be fixed in Trusty, too.
