Added that render_partial will always by default include a counter with value 1 unless there is a counter passed in via the local_assigns hash that overrides it. As a result, render_collection_of_partials can still be written in terms of render_partial and partials that make use of a counter can be called without problems from both render_collection_of_partials as well as render_partial #295 [marcel]
