Julian Foad commented on SVN-4840:
----------------------------------
I have checked some performance timings of the new svn_rangelist_merge2(), and
confirmed it is linear in total number of ranges to be merged (input1 + input2).
(On my laptop the raw speed was around 4 to 12 million ranges per second
depending on the patterns of overlap in the inputs. It is optimized for being
reasonably simple and efficient, not for maximum raw speed.)
