To be more precise than in my previous answer:

The documentation string of save-excursion says:

Save point, mark, and current buffer; execute BODY; restore those things.

In our situation, we only need to save and restore the value of
point.  I have often seen save-excursion used in such situations.

One could use the obvious:

(let ((opoint (point)))
     (goto-char opoint))

I doubt the gain in efficiency would be measurable to any degree, but
it certainly would be easy to change the code to use the above let
forms instead of save-excursion.
