doc: /* Non-nil means that Emacs should use caches to handle long lines more quickly.
Normally, the line-motion functions work by scanning the buffer for
-newlines. Columnar operations (like move-to-column and
-compute-motion) also work by scanning the buffer, summing character
+newlines. Columnar operations (like `move-to-column' and
+`compute-motion') also work by scanning the buffer, summing character
widths as they go. This works well for ordinary text, but if the
buffer's lines are very long (say, more than 500 characters), these
motion functions will take longer to execute. Emacs may also take
longer to update the display.

+If `cache-long-line-scans' is non-nil, these motion functions cache the
results of their scans, and consult the cache to avoid rescanning
regions of the buffer until the text is modified. The caches are most
beneficial when they prevent the most searching---that is, when the
buffer contains long lines and large regions of characters with the
same, fixed screen width.
-When cache-long-line-scans is non-nil, processing short lines will
+When `cache-long-line-scans' is non-nil, processing short lines will
become slightly slower (because of the overhead of consulting the
cache), and the caches will use memory roughly proportional to the
number of newlines and characters whose screen width varies.
