Thanks.

Three comments:

 - You changed "Return" to "Returns", but it is standard Emacs
practice to make the first line in a docstring imperative. From
(elisp) D.6 "Tips for Documentation Strings":

  For consistency, phrase the verb in the first sentence of a
  function's documentation string as an imperative--for instance,
  use "Return the cons of A and B." in preference to "Returns the
  cons of A and B."

- You didn't write ChangeLog entries. They are trivial in this case
(so no need to resend), but usually a patch should include them.

- This thead has been just Drew and you, and I'm not sure the result
is better. Though I understand Drew's arguments, it is still a bit
weird to me to look at the docstring of region-(beginning|end) and not
to see *any* reference to the region (yes, I know it is implicit in
"point or mark"). So I'd like to hear more opinions.
