There was a problem hiding this comment.
Observation, no change requested: This could be more strict, by verifying that the empty subrange is at the end. However, it's unlikely that we'll damage this (and this PR certainly isn't), so it's just something to keep in mind for future tests.

Fixes #1560
When avoiding an superfluous comparison we missed to add the necessary increment to exclude the first element of the last group.
