>Description:
	There is regression in BSD sort compared to GNU sort --merge option
	no longer works for stdin

	Upgrade from FreeBSD 8 to FreeBSD 10 caused breakage of our scripts
	where used constructions like:
	script_foo | sort ... | cut ... | sort -mu -k 1,1 | script_bar

>How-To-Repeat:

:~> cat ttt
key1    foo
key1    bar
key2    xzy
:~> cat ttt | sort -mu -k 1,1
:~>
:~> sort --version
2.3-FreeBSD

Expected result:

:~> cat ttt | sort -mu -k 1,1
key1    foo
key2    xzy
:~> sort --version
sort (GNU coreutils) 5.3.0-20040812-FreeBSD
