OK, I'll try to remove the whitespace changes.

I think Eli is pointing out that in every place where you made a modification to the code, you also changed the whitespace.  For example, you untabified all three lines of the following chunk.

-       (setq output
-             (format "This variable was introduced, or its default value was changed, in\nversion %s of Emacs.\n"
-                     custom-version))
+        (setq output
+              (format "This variable was introduced, or its default value was changed, in version %s of Emacs.\n"
+                      custom-version))
