Wow, that's disastrous!  And frightening: I use the "(set-window-buffer
(selected-window) (set-buffer ...))" idiom a lot in todo-mode.el; I just
checked two commands using `C-h f' followed by the command invocation:
one worked fine but the other caused the same disaster.  So now I have
to check all uses :(.  Is there a general guideline for when to use
set-window-buffer and when to use pop-to-buffer-same-window?

Anyway, I'll commit the dired.el change you recommend; many thanks.

Steve Berman
