Are there a lot of parentheses/braces there? are they nested?
This variable will only have any visible effect when both of the
following conditions are true:
. a physical line is very long
. the line includes many parentheses and/or braces, especially if
they are nested
If these conditions are not true, the variable will have no tangible
effect on redisplay performance.
Compilation buffers show errors and warnings, and this can easily
include strings. For example, a code line that calls 'message' in
Lisp or 'printf' in C usually includes a string. We don't want those
strings to be displayed incorrectly, unless displaying them correctly
takes a preposterous amount of time, at least not by default.
