From e32faa8adbc8ba9803088e849bc26680134c853c Mon Sep 17 00:00:00 2001

Subject: [PATCH] Remove "octopus".

We still advertise "git resolve" as a standalone command, but never
"git octopus", so nobody should be using it and it is safe to
retire it.  The functionality is still available as a strategy
backend.
