This is not a bug.  Erlang has always used 'behaviour' (and
'behaviour_info').  See
http://en.wikipedia.org/wiki/American_and_British_English_spelling_differences#-our.2C_-or

As a side note, Erlang allows for any user defined elements starting with -.

If you for example add the following line to your code

-my_own_local_thing(whatever_data).

then this is fully legal Erlang, and its effect is seen if you run
Module:module_info()

[...
{attributes,[{behaviour,[supervisor]},
              {my_own_local_thing,[whatever_data]}]},
...]

Cheers,
