Hi Jeremy,

I believe you can't advice a C function (not sure). In any case, advice
is generally best left as last resort. What's keeping you from defining
your own my-kill-buffer that'd call kill-buffer (which would switch to
the most recent buffer) and then do some buffer switching of your own?

Also see the docstring of kill-buffer. In particular, the docstring
tells you than it calls replace-buffer-in-windows, and then the source
code for replace-buffer-in-windows tells you that it calls
switch-to-prev-buffer. So if you must advice or redefine an emacs
function, these two look like better access points.

Just out of curiosity, what buffers are you trying to exclude?
