Backward Compatibility Notes
----------------------------
+ * Historically, the "-m" (mainline) option can only be used for "git
+ cherry-pick" and "git revert" when working with a merge commit.
+ This version of Git no longer warns or errors out when working with
+ a single-parent commit, as long as the argument to the "-m" option
+ is 1 (i.e. it has only one parent, and the request is to pick or
+ revert relative to that first parent). Scripts that relied on the
+ behaviour may get broken with this change.
