undo-kill-buffer

[Aaron Maxwell]

Hi, Does anyone know of an existing emacs function that will undo a 
kill-buffer command?  So like, if the user issues C-x k and then suddenly 
decides it was a mistake, they could just M-x undo-kill-buffer to get it 
back.

I have started coding this for myself.  If it's genuinely new and I'm not 
duplicating effort, then I will polish it and contribute to the main 
codebase.

Thanks,
Aaron
