Hi Andrew,

As a continuation of my former communication of January 25, and after having posted the attached patch in my personal page http://www.terra.es/personal2/danarag for about 3 months, feedback has come 
to me, and some bugs have been detected and corrected.

I believe that now (not before) the patch is really ready for merging into the main line if you consider it appropriate.

Thanks for your attention.
