Update to 1.21:
        * Improved the default output so it creates multiple formatted lines
          instead of single very long lines for each hit.
          Use the new "--singleline" (-S) option to get the original
          "long line" format.
        * Removed duplicate "getpass" entry in the ruleset;
          this didn't hurt anything, but was unnecessary.
          Thanks to the user who gave me that feedback, wish I'd kept your
          email address so I could credit you properly :-).
        * Added a short tutorial to man page.
        * Fixed initial upper/lower case on many entries in the ruleset.
        * Allow "--input" as a synonym for "--inputs".
