 * r1513879, r1513880, r1515516
   Fix packed revprop file splitting logic in FSFS
   Justification:
     Modifying revprops may result in the loss of revprops for one
     or multiple revisions.
   Branch: ^/subversion/branches/1.8.x-r1513879
   Notes:
     I added r1515534 to the branch as an obvious fix.
