| 20 | -l LENGTH Try to limit log lines to LENGTH characters (default 79). |
| 21 | -R If no FILEs are given and RCS is used, recurse through working directory. |
| 22 | -r OPTION Pass OPTION to subsidiary log command. |
| 23 | -t TABWIDTH Tab stops are every TABWIDTH characters (default 8). |
| 24 | -u "LOGIN<tab>FULLNAME<tab>MAILADDR" Assume LOGIN has FULLNAME and MAILADDR. |
