Well a \n is inserted actually, not \r, but yes that is a problem on windows.
This demonstrates the behavior:

  $ printf '2\r\n1' | sort | od -Ax -tx1z -v
  000000 31 0a 32 0d 0a                                   >1.2..<

The \n is inserted so as to delimit the reordered item appropriately,
which is set here:

http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=blob;f=src/sort.c;h=c2493192;hb=HEAD#l178

It seems that this should be set to '\r\n' on cygwin builds,
(wither other adjustments to handle multiple chars).

thanks,
Pádraig.
