Log Message:
	Fix potential directory existing info leak in sudoedit.
	When creating a new file, sudoedit checks to make sure the parent
	directory exists so it can provide the user with a sensible error
	message.  However, this could be used to test for the existence of
	directories not normally accessible to the user by pointing to them
	with a symbolic link when the parent directory is controlled by the
	user.  Problem reported by Matthias Gerstner of SUSE.
