But luaL_loadbuffer can't know whether the buffer actually came from a
file, and whether it was from the start of a file. So it makes more
sense for loadbuffer to accept only valid lua chunks, and require that
the caller handle any such details. (The other thing that dofile checks
that loadbuffer does not is whether the file starts with a BOM.)
