Thanks for spotting @wufeipeng. Fortunately, rippled is not currently using getPrev anywhere at this time. Before considering a merge, I want to investigate replacing RangeSet with Boost ICL as an alternate. I'll post back here once done evaluating that option.

Thanks again for your contribution, but I believe we will go with #2113 instead. Better to remove code that is not needed or used!

understand, that is fine.
