41 * curbuf->b_u_curhead points to the header of the last undo (the next redo), | |
758 | 42 * or is NULL if nothing has been undone (end of the branch). |
7 | 43 * |
753 | 44 * For keeping alternate undo/redo branches the uh_alt field is used. Thus at |
45 * each point in the list a branch may appear for an alternate to redo. The | |
46 * uh_seq field is numbered sequentially to be able to find a newer or older | |
47 * branch. | |
