Part of r245761 makes "grep -D skip" broken for pipes, i.e.
	echo xxx | grep -D skip xxx
returns nothing. Instead of just removing added S_ISFIFO condition
(originally absent in this version of grep), make it work as latest
GNU version does: don't skip directories and devices if fd == STDIN_FILENO.
