    Tidy up failed-test reports.
    
    There was a pointless blank line in the middle; exit statuses look
    silly in quotes; and really there's no reason not to put the status
    and output on the same line.

    Implement the Lambert W function.
    
    Both branches, of course. W(x) is valid for x >= -1/e and is always at
    least -1, and Wn(x) is valid for -1/e <= x < 0 and is always at most -1.
    
    This is a function I've occasionally run into in the past, and since
    it fits naturally into today's new MonotoneInverter framework, this
    seems like a good moment to add it to the spigot collection.
