Someone said you might be misreading your message, you aren't. This issue actually has to do with your <project>/.git/config
file. In it will be a section similar to this:
[remote "origin"]
url = <url>
fetch = +refs/heads/*:refs/remotes/origin/*
If you remove the fetch line from your project's .git/config file you'll stop the "Your branch is ahead of 'origin/master' by N
commits." annoyance from occurring.
Or so I hope. :)
