	Don't set cmd[0] to the window ID

	Ahoy,

	the attached patch fixes a tiny issue with tabbed. When running it
	without a command and having it run spawn(), it tried to execute its
	window ID as a command. While most people probably don't have
	executables called 341123 or the like in their path, I think that is not
	exactly intended. The following patch fixes that:

	Subject: [PATCH] Don't set cmd[0] to the window ID

	Starting tabbed without a command sets cmd[0] to the window ID of
	tabbed. This leads to funky errors such as "execvp: <ID> failed: no such
	file or directory" when running spawn().
