I'm not sure that's correct.  All the .txi files are simply included
in the overall octave.texi file which is used to generate a single
octave.info (or .pdf or ...) file.  So I think all references would be
of the form

  @ref{ANCHOR,,FCN,octave}

For example,

  @seealso{svd}

would be transformed to

  @seealso{doc-svd,,svd,octave}

It should be fairly easy to do this in the munge-texi.cc program,
even if you don't know much C++.

But it would also be OK to rewrite it as an Octave script as I don't
think there is a real need for it to be done in C++ (unless the script
version takes an unreasonably long time to run).
