If you call `git log --raw` (possibly adding --all) and then search for 8dd1e55, you should at least get to the revision when this file was changed to the revision that served as base for the patch. To make it faster, you could call `git log --raw -- <filename>`. That would also have the advantage that you could scroll up again to see which revision, if any, modified the file again, giving you kind of a commit range from which to pick.

Ciao, Johannes
