rebase: do not add second parent to rebased changeset (drop detach option) (BC)
Rebase now behaves as if --detach was always passed. Non-merges are rebased as non-merges, regardless of their parent being an ancestor of the destination. Merges will usually be rebased as merges unless both of their parents are ancestors of the destination, or one of their parents is pruned when rebased. This only alters the behavior of rebase when using the --source/--rev options. --detach option is deprecated. All test changes were carefully validated.
