I think it is a little more subtle than that. People may be using it
under the expectation that point and mark will also be saved in the
buffer accessed by set-buffer.


Hi Tim, Hi Uday,

wherefrom you assume that?

AFAIU buffer, point and mark are stored the very moment `(save-excursion' cames in.

They should be restored if the parentese closes.
Every setting of buffer, mark and point between then doesn't matter as far as the buffer now current again is concerned.

Maybe there have been other `save-excursion' intercurse. But every one tells it's own story.

What's the difficulty?

Andreas
