As I don't wan to waste code for testing the version, when do we change 
this? Now? I downloaded version 1 so it is available for all platforms.

there's one more file: grph-con.lua ... (the merged file is not relevant 
as it is for generic but no one uses that one for fonts (like emoji) 
that use svg and the merged file is generated from other files anyway)

Here I also need to adapt the font-ocl replacement file (font-ocm) which 
reminds me that i need to add some already long pending code to the 
luatex binary one of these days.
