is this a feature of zsh-3.1.6?

Hi.

	The following does not produce output to screen on FreeBSD-3.4:

#include <stdio.h>

int main (void)
{
   printf ("Hello World\n");

   return 0;
}

c74763-a% ./hello
c74763-a% ./hello | strings
Hello World


	When '\n' is added to printf:

#include <stdio.h>

int main (void)
{
   printf ("Hello World\n");

   return 0;
}
c74763-a% ./hello
Hello World


However, when running under /bin/sh, all works.

Please suggest something :-)
