They shouldn't call it:

    This function is usually the wrong thing to use in a Lisp program.
    What you probably want is a loop like this:
      (while (re-search-forward REGEXP nil t)
        (replace-match TO-STRING nil nil))
    which will run faster and will not set the mark or print anything.
