Documentation

Jit-lock asks to fontify chunks of at most this many characters at a time.

The actual size of the fontified chunk of text can be different, depending on what the fontification-functions actually decide to do.

This variable controls both display-time and stealth fontifications.

The optimum value is a little over the typical number of buffer characters which fit in a typical window.
