Before upgrading to the newest version, we used to be able to right-click a commit and select "Reverse Commit..." in order to run a `git revert` on that commit.
Now, it gives this error:
git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks revert --no-edit -m 1 {SHA}
error: mainline was specified but commit {SHA} is not a merge.
fatal: revert failed
Completed with errors, see above.
Note that we do not use merges. I was just trying to revert a commit, I have no idea why it would specify -m. This used to work fine on a previous version of SourceTree.
