At Emacs 20, replace-string only took three args, i.e. it did not optionally
restrict replacements to a region.

At Emacs 21, two optional args were added to provide this region capability.
Since these are optional just edit the command perhaps to:
        (replace-string "foo" "bar" nil (point) (mark))
if you want to do it on a different region.

Or, don't forget that you can use M-p and M-n in the replace-string
interactive prompt to retrieve
previously entered strings.

Or, use narrow to region first.
