Sorry, I misread it a bit and understood as part of illustration that
there are still no consistency even after dropping luaL prefix.

Moved <struct lua_State *> to the end of an argument list.

Removed the following paragraph from the commit message:

 | Changed order of luaL_merge_source_tuple_fetch() arguments to unify it
 | with other functions (<struct lua_State *>, <struct merge_source *>).
