The ean13 version can’t cope with complete numbers but insists on
calculating the checksum itself. That’s a bit cumbersome since I
usually have my complete ISBN in a variable.
There’s a spurious ">" after the EAN.

line 321:
local function ean(str,quietsign)
line 440:
insert(list_one,quietsign and ">" or "~")
line 457:
generators["ean13"] = function(str) return ean(str,false) end
generators["gtin13"] = function(str) return ean(str,true ) end
Thank you! That works (of course).
Now, could you also allow to provide the check digit by the user instead
nulling the number?
