 - Add tests for:
 - Test delete-around-word/WORD
+  - Delete-around-word has tests for when cursor is on space (needs tests for alpha and punctuation too)
 - Reimple `%` motion and `d%` motion.
   - They should both search for the next character in any pair, the same way in Vim
   - Add tests for reimplemented movements and motions
