Re: 5-arg xref to Top w/o 3rd arg

[Karl Berry]

    But other output formats may be affected, at least docbook and HTML
    which nowadays are more similar with TeX output than with info.

So ... can you make those changes to Docbook and HTML a la what I just
did to texinfo.tex, if not already done?  ("See @cite{The GNU Emacs
Manual}" when no node/section name is given.)  My ad hoc test file is
below.

Thanks,
k

\input texinfo
@setfilename xref5.info

@node Top

@xref{,,, emacs, The GNU Emacs Manual} (empty node name).

@xref{TeX Mode, ,@TeX{} Mode, emacs, The GNU Emacs Manual}.

Rest have nodename Top.

@xref{ Top,,,../emacs, The GNU Emacs Manual} (space before).

@xref{Top ,,,../emacs.info, The GNU Emacs Manual} (space after).

@xref{Top,,,/foo/emacs, The GNU Emacs Manual}.

@xref{Top,,,/foo/emacs.info, The GNU Emacs Manual}.

@example
@xref{Top,,,/foo/, The GNU Emacs Manual} (in example).
@end example
