>Description:
	if file redirection is failed, the exit status ($?) for the command
        is 0, that is incorrect.

        In Shell and Utilities volume (XCU)
        http://www.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html#tag_02_08_02
        2.8.2 Exit Status for Commands
         ...
        If a command fails during word expansion or redirection,
        its exit status shall be greater than zero.

>How-To-Repeat:
	$ ls < no_such_file; echo $?
	sh: cannot open no_such_file: no such file
	0
	$
