+       * doc/texinfo.tex (\xrefX): Add a comma after the page number 
+       only if the cross-reference command is followed by a space, 
+       instead of listing possible punctuation characters.  Suggestion 
+       from Karl Berry.

        * doc/texinfo.tex (\indexnofonts): Add % after \} and \{ because 
        spaces are not skipped there.
