set diff box recursion limit to UINT_MAX by default

In practice, recursion is already limited by our Myers max-effort cut
and this heuristic should generally provide a better split than a limit
on the number of diff boxes.

A recursion limit is only required for diff configs that do not
include the Myers algorithm, which we currently don't have.

Discussed with Neels
