[Dev-luatex] platform specific functionality

Hi, With the other thread asking to add readlink, I would also like to ask for an addition of Windows specific GetShortPathName. Without this function it is impossible to check if two paths point to the same place. However, I'm not sure if beefing up LuaTeX with this kind of functionality is the best thing to do (there will be undoubtedly other things worth adding). Perhaps external modules? What's the status of loading binary modules? Will this be available for the coming TL release? And another request if I may. With kpsewhich it is possible to specify a search path explicitly with the -path switch, but this functionality is not exposed through lua kpse lib. Could this be added? Cheers, Tomek
