Filtering parameters inside arrays when logging

Hi,

This is my first post here. I've stumbled upon this while creating an
application which makes use of nested forms. Basically, I have an
Account model which has many Users. When I create the account it
creates one User. The action receives parameters like:

:account => { :name => 'foo', :users_attributes => [{ :login =>
'foo', :password => 'secret', :password_confirmation => 'secret' }] }

Since my controller has the following line:

filter_parameter_logging :password, :password_confirmation

I was expecting to see both password and password_confirmation
filtered, but they weren't. Looking inside filter_parameter_logging I
understand that it didn't treated arrays. I've made a patch, but it
seems rails.lighthouseapp.com is down, so I'll just post it here. The
patch contains changes to both code and tests. I've made it by
branching origin/2-3-stable.

Thanks

Here it is:

Just added a ticket in lighthouse:

I couldn't do it earlier because it was down on Friday.
