[Bug-ed] Inconsistency between BSD ed(1) and GNU ed(1)

[Tim Chase]

Steps to recreate:

  address@hidden ed
  a
  x1
  y2
  y3
  .
  2
  -,+s/x/y/p
  y1
  .=
  1

BSD ed (tested both OpenBSD 6.2 and FreeBSD 11) leaves you on line 1
(the only/last line changed)

  address@hidden ed
  a
  x1
  y2
  y3
  .
  2
  -,+s/x/y/p
  y3
  .=
  3

GNU ed (tested Debian Stable & Ubuntu 16.04LTS) leaves you on line 3
(the end of the range)

Thanks,
