    Vincent Lefèvre reported experiencing an index display performance
    issue.  This occurred with messages containing many recipients.  He
    had many index color lines containing ~l.  The ~l ended up being run
    over and over on these messages, resulting in a noticable slowdown
    displaying the index.
    
    This patch adds caching for just a few of the pattern operations (~l,
    ~u, ~p, ~P) that are potentially expensive and also don't have
    arguments.  The caching is only enabled for operations repeatedly
    matching against the same message: color, hooks, scoring.
    
    The caching is fairly targeted, but isn't that invasive or
    complicated.
