New Revision: 1713104

URL: http://svn.apache.org/viewvc?rev=1713104&view=rev
Log:
Remove another redundant element from FSX' packed revprops description struct.

* subversion/libsvn_fs_x/revprops.c
  (packed_revprops_t): MANIFEST_START is the same as MANIFEST[0].START_REV.
  (get_revprop_packname, 
   repack_file_open): Determine the MANIFEST_START locally where needed.
