Original issue's description:
> Segment strings on dot and comma in addition to space and tab
> 
> Add dot and comma do the list of word separators in an effort to prevent
> hitting the long-word performance cliff when shaping JSON and JS source.
> 
> This is a speculative change based on reported observations as we've yet
> been able to reproduce this problem. We do know that performance suffers
> somewhat for very long words though, eminently for fonts with ligatures.
