A nobuflisted buffer will be jumped to after killing the last buffer

[linjiX]

After killing the last buffer in a window, normally we will get an empty buffer.
But if a nobuflisted empty buffer exists (some plugins will leave nobuflisted empty buffer),
we will jump to this nobuflisted buffer.

I think it will be better to not jump to a nobuflisted buffer.
Could you fix it or make it configuable.
