The count option for statuses/retweets does not work as specified. Consider a Tweet that has been sufficiently (more than 100 times) retweeted, such as http://twitter.com/twitter/status/6227052301
Getting retweets of this status through the following call http://api.twitter.com/1/statuses/retweets/6227052301.xml results in 20 retweets being returned. We can correctly limit the number of retweets returned by doing http://api.twitter.com/1/statuses/retweets/6227052301.xml?count=2. However, we cannot return up to the last 100 retweets as specified in the API by making count larger than 20. For example, http://api.twitter.com/1/statuses/retweets/6227052301.xml?count=50 only returns the 20 most recent retweets. Thanks, Brendan
