I don't have my NEC 2005 to verify (left it at work), but IRC 2003 has an illustration (Fig E3801.2) of a short wall behind a door being explicitely counted as part of the 6' but not requiring a receptacle by itself.
I'm curious- am I the only one who refers to IRC as opposed to NEC when looking for electrical code on simple residential things? In VA at least, NEC is only invoked because it's a reference of IRC/IBC and it's not itself ever called out by law. So, the electrical portion of IRC is every bit as legally binding, and generally nicely condensed.
