+Looking at those files, all the duplicated files
+are located at least 2 subdirectories deep, and most more like 5-7
+deep. But, almost all of the repo is inside such
+subdirectories, so that is not conclusive.
+
+Aha! I managed to reproduce it:
+
+	joey@darkstar:~/tmp/t#master(unlocked)>mkdir ook
+	joey@darkstar:~/tmp/t#master(unlocked)>cd ook
+	joey@darkstar:~/tmp/t/ook#master(unlocked)>mkdir boop
+	joey@darkstar:~/tmp/t/ook#master(unlocked)>cd boop
+	joey@darkstar:~/tmp/t/ook/boop#master(unlocked)>mkdir beep
+	joey@darkstar:~/tmp/t/ook/boop#master(unlocked)>cd beep
+	joey@darkstar:~/tmp/t/ook/boop/beep#master(unlocked)>mkdir yeep

+Ok, it seems it's simply caused by deep paths in the tree and nothing
+else. Will debug from here.
