I'm not sure where to look. I would expect a loop like:

    while(templateFile) {
        templateFile.getline(buff, BUFSIZ);
        // ?? debug echo to the console
        fprintf(stdout, "%s\n", buff);
        // loop until there is a complete syntax element
        while(!luaL_loadbuffer(L, buff, strlen(buff), "Line") {
            templateFile.getline(buff, BUFSIZ);
        }
        // execute the complete chunk on the stack
        int iError = lua_pcall(L, 0, 0, 0);
        if(iError) {
            ...
            break;
        }
    }

where I would keep on calling luaL_loadbuffer(...) until the syntax analyser 
said that the last syntax element was complete.  luaL_loadbuffer(...) seems 
to only return

As far as I can see, there's nothing like this in lua.c. It seems that 
lua_load(...) (or luaL_loadbuffer) should return an status code that implies 
"Needs more input."
