mm-util.el question

[Miles Bader]

In merging some of Stefan's Gnus changes from the Emacs tree into the Gnus
trunk, I ran across this change, which I'm not sure about, in mm-util.el:

@@ -75,4 +93,5 @@
      (string-as-multibyte . identity)
+     (string-to-multibyte . mm-string-as-multibyte)
      (multibyte-string-p . ignore)
      ;; It is not a MIME function, but some MIME functions use it.
      (make-temp-file . (lambda (prefix &optional dir-flag)

The Gnus trunk already has an entry for `string-to-multibyte':

     (string-to-multibyte
      . (lambda (string)
          "Return a multibyte string with the same individual chars as string."
          (mapconcat
           (lambda (ch) (mm-string-as-multibyte (char-to-string ch)))
           string "")))

So is the more complicated Gnus version necessary, or would Stefan's version
(making `mm-string-to-multibyte' the same as `mm-string-as-multibyte') work
as well?

Thanks,

-Miles
