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)) Clément.
