[tex-live] serious TEXINPUTS bug in texi2dvi

[Karl Berry]

    the current texi2dvi ... no longer handles TEXINPUTS values
    correctly which contain braces.  

I've made the change below, and installed the current texi2dvi in TeX
Live (all platforms).  Let me know if problems persist (wouldn't
surprise me).

Thanks,
karl
