Johannes SixtWhen the first commit is manufactured, its parents are looked up in the commit map. However, without this patch the map is always empty at that time. If the entire history is rewritten, this is no problem because the first commit does not have any parents anyway. However, if -r is used to constrain rewriting to only part of the history, this first commit is manufactured incorrectly without parents because 'cat' fails.
