 * When merging `releaseX` branch into `master`, we should only use the release note from the `master` branch,
 * but sometimes changes on release notes.md was brought to master and merged unnoticed,
 * e.g https://github.com/gradle/gradle/pull/25825
 *
 * This script is to check if there is any merge commit that brings changes from release branch to master.
 * Usage: groovy CheckBadMerge.groovy <commit1> <commit2> ...
