7 + * Historically, the "-m" (mainline) option can only be used for "git

8 + cherry-pick" and "git revert" when working with a merge commit.

9 + This version of Git no longer warns or errors out when working with

10 + a single-parent commit, as long as the argument to the "-m" option

11 + is 1 (i.e. it has only one parent, and the request is to pick or

12 + revert relative to that first parent). Scripts that relied on the

13 + behaviour may get broken with this change.
