Actually there is another problem: whereas it's easy to rely on the
variable sentence-end-double-space as was asked by this request:

diff --git a/lisp/textmodes/paragraphs.el b/lisp/textmodes/paragraphs.el

   (interactive (list nil (use-region-beginning) (use-region-end)))
   (let ((regexp "\\([]\"')]?\\)\\([.?!]\\)\\([]\"')]?\\) +")
-        (to-string "\\1\\2\\3  "))
+        (to-string (concat "\\1\\2\\3 "
+                           (if sentence-end-double-space
+                               " "
+                             ""))))
     (if no-query
         (progn
           (when start (goto-char start))

But the problem is that when a user customized
sentence-end-double-space to nil, the user still
might want to put two spaces since the docstring says:

  "Put two spaces at the end of sentences"

So using one space will contradict the docstring.
