Pressed standard Commit button instead of "Complete" merge, following successful conflict resolution of a merge from a commit that's "mid stream" on one branch, to the head of another branch.

Steps to reproduce

1. Merge from a commit that's mid-stream on one branch, to the head of another branch.
2. Ensure this merge will get at least one conflict to resolve.
3. (For me, this was a big merge involving MANY files but few conflicts. No idea if this contributes to the error or not.)
4. Resolve the conflicts.
5. Shut down and re-start Git Extensions.
6. Press the standard "Commit" button, NOT the "Continue" (merge) button.
7. (Possible contributing factor: specified 30 previous commits to be added into the comment. It's a LONG comment that needs editing.)
8. Get the Index out of Range exception.

Did this work in previous version of GitExtensions?
