This prevents larger files from causing latency and lag, especially
large YAML files, like generate Kubernetes menifests.
This fix here simply does not enable highlighting indentation levels if
the file is above 100KB in size. In my experience it's rare a file meant
to be manually edited by a human is above 100KB in size.
This should offer a more reliable means of running `whitespace-cleanup`
on buffer save than whitespace-mode's whitespace-action setting. Also it
allows for easily toggling whitespace clean up off by disabling
whitespace-clean-mode.
Previously prettier would always format markdown files to 80 character
long lines. Now it reads the character width from the fill-column
variable in such a way that fill-column can be set with dir-local
variables.
This allows specific major-modes to disable hl-line-mode, which is
desired some terminal/shell modes like vterm where the hl-line flickers
constantly while typing.
