No protection against abnormal exits or changes to the mark. The
more important issue is abnormal exits, eg, if a search fails, since
code shouldn't mess with the mark anyway.
Which brings up a question for Stefan. Are you saying that the
condition-case-save-point-and-mark aspect of `save-excursion' should
be abstracted out (say as `save-region') and separated from the
save-buffer aspect?
