Log Message:
	Better support for "sudo -b" when running the command in a pty.

	When a command is run via "sudo -b" it has no access to terminal
	input.  In non-pty mode, the command runs in an orphaned process
	group and reads from the controlling terminal fail with EIO.  We
	cannot do the same while running in a pty but if we set stdin to a
	half-closed pipe, reads from it will get EOF.  That is close enough.
