Oh, yes, ibuffer.  Probably it's cool, but for me it's a bit overloaded
with features.

The intent for the commands above was to simplify buffer set cleanup
(which I do at most daily).  Like extended `kill-matching-buffers'.

Maybe add a few commands similar to `kill-matching-buffers' instead of
extending buffer-menu?  A user option could be used to control whether
to query or not (I don't want to be queried 100 times in a row).
