 * `git_rebase_no_changes` – runs `git rebase --skip` instead of `git rebase --continue` when there are no changes;
 * `git_rm_local_modifications` –  adds `-f` or `--cached` when you try to `rm` a locally modified file;
 * `git_rm_recursive` – adds `-r` when you try to `rm` a directory;
+* `git_rebase_merge_dir` – offers `git rebase (--continue | --abort | --skip)` or removing the `.git/rebase-merge` dir when a rebase is in progress;
 * `git_remote_seturl_add` – runs `git remote add` when `git remote set_url` on nonexistant remote;
 * `git_stash` – stashes you local modifications before rebasing or switching branch;
 * `git_two_dashes` – adds a missing dash to commands like `git commit -amend` or `git rebase -continue`;
