Documentation
The amount to expand the start and end of the region when fontifying.
This should be a cons cell (START . END). When fontifying a buffer, Emacs will move the start of the query range backward by START amount, and the end of the query range by END amount. Both START and END should be positive integers or 0. This doesn't affect the fontified range.
