What is the proper behaviour for save-excursion? The emacs-lisp intro and
the docstring seem to have slightly differing explanations - namely, the
docstring mentions that it saves current-buffer as well as point and mark,
and the emacs-lisp intro does not. Based on just what it does, I'm not
entirely sure which is correct - the following code snippet, executed in
*scratch*, returns the "*scratch*" buffer but the buffer displayed is the
"bar" buffer, and evaluating current-bufer afterwards returns the "bar"
buffer.
(progn
(save-excursion
(switch-to-buffer "bar"))
(current-buffer))
Either the manual or the docstring should be changed to reflect what it
does, but I'm not entirely sure which based on this.
Thanks,
Nathaniel Flath
