This means changing several places in Emacs and still breaking
compatibility with external packages, and all this hassle just
for fixing a minor problem.  I think this fix is disproportional
to the problem.

OTOH, my latest patch implements exactly what is needed: using your
suggestion to place code in the interactive spec of switch-buffer-*,
it also sets a special function minibuffer-default-add-function
that removes the current buffer from the list of defaults of
switch-buffer-* commands.  Thus, this is a very localized fix.
I spent enough time trying hard to find a better solution,
but I see no better.  I propose to install this fix and
move to more important things.
