kill-matching-buffers

[sds]

I find the appended patch quite usefull.
is this functionality already available elsewhere or are there any other
objections to this patch?

Emacs is in pretest---no new features, please.

Anyway, it seems like there are good (and arguably better) ways to do
this in emacs already -- e.g. in ibuffer you can do

   %n regexp RET D

or

   /n regexp RET t D

In either case you have a chance to adjust the set of files to be
deleted before hitting D.

It might be useful, but now is not the time for new features.
