Why would that make a difference? When I try `master` with this set to
100000, the file still shows up with font-locking, so apparently it's
been fully font-locked despite `max-redisplay-ticks` and after that
font-locking (and syntax-propertize) won't make any difference any more
(until the buffer is edited) since they're already done.
[ Of course font-locking (and syntax-propertize) still do have an
effect in that the text-properties they applied can impact the time it
takes for the redisplay to do its job; so by "won't make any difference"
I mean that 0-cycles will be spent running font-lock of
syntax-propertize code. ]
