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().
