Re: instopt_portable

Hi Ernst,

    I spent lots of time on asking myself why my setting 
    of TEXMFHOME,TEXMFVAR and TEXMFCONFIG
    has been ignored, and it is because i uchoose instopt_portable 1. 

Thanks much for the report. I'll look into updating the
docs/texmf.cnf/whatever after the release. --best, karl.
