You're definitely better versed in this problem than I am, so +1 to
whichever way you want to go. But FWIW, my instinct would be to go the
tree-checksum route. Once we have tree checksum APIs, we will probably
find them useful for other things. Whereas the proposed new
implementations of the svn_wc_diff_callbacks3_t functions would clearly
only be useful for this one situation, because, as you say:
