[XeTeX] fontspec and Nikosh font

[maxwell]

Not sure if Will is on this mailing list, but I'm cc'ing him using his 
email address on the fontspec document.  (The doc doesn't have the 
co-author's email, Khaled Hosny, but I think I've seen him here.)

I confirm that omitting 'dev2,' from that declaration causes fontspec 
not to emit a warning when I do
     \newfontfamily\sanskritfont[Script=Devanagari]{gargi}
and similarly for the Nikosh font, fontspec gives a warning when I do
     \newfontfamily\bengalifont[Script=Bengali]{Nikosh}
unless I change
     \newfontscript{Bengali}{bng2,beng}
to
     \newfontscript{Bengali}{beng}
in fontspec-xetex.sty.

Thanks for the pointer, Jonathan!
