Good, I'll make it so.  By the way, why is the default
‘lazy-highlight-buffer-max-at-a-time’ (20) so low?  The overhead of
creating a timer for every 20 matches is pretty substantial.  On my
machine, a value like 500 or 1000 makes the lazy count finish visibly
faster, and doesn't affect responsiveness even in huge files.
