This should be soon in 'master', you can check it in 'next', and I think it would be present in the new release.

From "What's cooking in git.git (Jul 2016, #09; Fri, 29)": -------------------------------------------------------------------- [Cooking]

* da/subtree-2.9-regression (2016-07-26) 2 commits
  (merged to 'next' on 2016-07-26 at 9d71562)
 + subtree: fix "git subtree split --rejoin"
 + t7900-subtree.sh: fix quoting and broken && chains
 (this branch is used by da/subtree-modernize.)

 "git merge" in Git v2.9 was taught to forbid merging an unrelated
 lines of history by default, but that is exactly the kind of thing
 the "--rejoin" mode of "git subtree" (in contrib/) wants to do.
 "git subtree" has been taught to use the "--allow-unrelated-histories"
 option to override the default.

 Will merge to 'master'.
