The issues API filters out closed issues by default
GET /issues.xml API only shows open issues when called without arguments.
For an API it is strange to apply such a filter by default?
I understand that the API uses the same code as the web interface for queries, but an API does not show that this default filter is on, as the web interface does.
(adding a warning/notice in the API docs would be nice too for versions where this is already the norm)
