Well, this is at the Lua level, not the C API, but I have often missed
the absence of Lua access to lua_concat. The big point being that
lua_concat respects metamethods but table.concat does not.

Of course, the `n` parameter of lua_concat would be the number
of items given. `select` can be used at the Lua level if necessary.
