> hl.fragsizeIsMinimum was added in 8.5 with a default setting of false -- thus
> producing _average_ length fragments of fragsize instead of _minimum_ beyond
> fragsize. In previous releases, even though the setting didn't exist, it was
> in-effect true (minimum). Unfortunately, this flip was found to be a
> significant performance regression for highlighting lots of text (especially
> when using the SENTENCE break iterator), and furthermore it seems to be of
> relatively minor value in fragment sizing.
> I propose we flip this back to true.
