Re: Hook for "buffer switched"

I think generally the answer is "no", tho this question is ill-formed:
it's not clear what you mean by switching buffer: do you mean "change
the currently active buffer" (i.e. what is done by `set-buffer'), or
"change the buffer displayed in the current window", or "select
a different window showing a different buffer", or ...

Maybe because to a large extent it's an ill-defined problem and once
they try to define it better, people seem to end up deciding they don't
really need to solve it any more?
E.g. often the original problem of the OP becomes simply unsolvable in
the general context, such as when a buffer is displayed in several
windows at the same time.
