- * Identifies the edits which are present between {@code commitA} and {@code commitB} due to other
- * commits in between those two. Edits which cannot be clearly attributed to those other commits
- * (because they overlap with modifications introduced by {@code commitA} or {@code commitB}) are
- * omitted from the result. The edits are expressed as differences between {@code treeA} of {@code
- * commitA} and {@code treeB} of {@code commitB}.
- *
- * <p><b>Note:</b> If one of the commits is a merge commit, an empty {@code Multimap} will be

- * <p><b>Warning:</b> This method assumes that commitA and commitB are either a parent and child
- * commit or represent two patch sets which belong to the same change. No checks are made to
- * confirm this assumption! Passing arbitrary commits to this method may lead to strange results
- * or take very long.
- *
- * <p>This logic could be expanded to arbitrary commits if the following adjustments were applied:
- *
- * <ul>
- * <li>If {@code commitA} is an ancestor of {@code commitB} (or the other way around), {@code
- * commitA} (or {@code commitB}) is used instead of its parent in this method.
- * <li>Special handling for merge commits is added. If only one of them is a merge commit, the
- * whole computation has to be done between the single parent and all parents of the merge
- * commit. If both of them are merge commits, all combinations of parents have to be
- * considered. Alternatively, we could decide to not support this feature for merge commits
- * (or just for specific types of merge commits).
