Description:
use of $(< filename | program) does not work. It either should or it
should be properly documented.
The problem also happens on bash4.
Repeat-By:
qq=$(< /etc/passwd | grep sys)
echo $qq
# result is null
Fix:
Either fix the docs to tell people that a pipe is not allowed or fix
the code to allow it.
The problem is not the pipe but the fact that '<filename' is an empty
command which does nothing. If you want 'program' to read from 'file',
use 'program<file'.
