The new command `git rebase --show-current-patch` is useful for seeing the commit related to the current rebase state. Some however may find the "git show" command behind it too limiting. You may want to increase context lines, do a diff that ignores whitespaces... For these advanced use cases, the user can execute any command they want with the new pseudo ref REBASE_HEAD. This also helps show where the stopped commit is from, which is hard to see from the previous patch which implements --show-current-patch.
