There's nothing to explain that can be easily explained to someone who
isn't privy to the display code internals. What does "redisplay
ticks" tell you intuitively? Chances are your intuition is correct.
The mechanisms behind that variable are not important, as long as our
recent measures to cope with very long lines do their job, so I see no
reason to document the ticks stuff more than it already is. If you
are really interested, grep the sources for update_redisplay_ticks.
