Good point... but don't always assume that save-excursion is really
going to save what you think it will.  Every now and then I find
a case where it doesn't seem to want to restore the current buffer,
and I need to do that manually.

(No, I haven't yet filed a bug report.  Maybe next time I see the
problem.)
