Are you sure? As far as I can tell the API as currently implemented
was pretty buggy. It would update the data that the FS implementation
sent to the sqlite backend without actually updating the svn:mergeinfo
properties in the FS itself. What does svn_fs_change_mergeinfo offer
that svn_fs_change_node_prop doesn't?
