New Revision: 1816966

URL: http://svn.apache.org/viewvc?rev=1816966&view=rev
Log:
Fix an assertion in 'svnfsfs stats' with pre-v4 FSFS repositories.

* subversion/libsvn_fs_fs/fs_fs.c
  (svn_fs_fs__min_unpacked_rev): MIN_UNPACKED_REV is always well-defined but
                                 updating it is prohibited for non-packable
                                 repos (so we would catch bugs in our logic).
