Problem: It would be nice to be able to see the block history for individual IPs on a range when viewing the range's contribution history, both past and present. This is useful when evaluating whether a rangeblock against a vandal is desirable, what IPs the block needs (or doesn't need) to reach, and what blocks might be superseded if a rangeblock is imposed, a problem I've noted before.
Proposed solution: Allow block history for a range to be visible in the range's contributions history.
Who would benefit: Everybody who would benefit from more efficient blocking.
