* -r is for the revision to start taking history from. If you want to include all of the history, just leave that option off, but it will take a very long time, and you really don't need all of it. The older a revision you choose, the longer it will take to import. But you will not be able to "git blame" past the earliest revision you import. Choose wisely.
