We changed the default some time ago at the request of an, er, customer
who was distressed at seeing files with \n's and no \r\n's.

Pipes have nothing to do with this.  The standard output of a program

run outside of a cygwin environment.

Undoubtedly the documentation has not been updated to reflect this.
