I see that that the Lua 5.1.4 (the current Lua) that wxLua uses pushes
the global table "arg" in wxLua/modules/src/lua.c. Is the "..."
construct in 5.2?

I don't think this function should push an "arg" table for each Lua
file executed. It's unclear to me what would be in the "arg" table. In
the wxLua apps wxLua and wxLuaFreeze the "arg" table is created from
the command line params, but a C++ app that uses wxLua to run scripts
may not have an "arg" table at all. In fact this function may be run
after user code has been run which may have changed the "arg" table.
I do think there should be a way to put args on the stack for the
RunFile() function. Maybe the function should have this signature:
int wxLuaState::RunFile(const wxString &filename, int nresults, int nargs)
...
int status = luaL_LoadFile(wx2lua(filename));
if (status == 0)
{
if (nargs > 0) lua_Insert(nargs); // put compiled script below args
status = LuaPCall(nargs, nresults); // nargs and nresults
