Hi,

I just wanted to know, what the final maintainers' decision about inclusion of 
the iso* into the core Octave sources is? I think that I can work on creating a 
changeset because I don't want these codes get forgotten...

If you say you currently can't decide or you think it is better to not include 
the files right now or whatever then I think we should at least host Martin's 
functions at OF right now?

Best regards,

PS. Will my patch for __patch__.m be applied? Cf.
