Revision 1461405

Reintegrate the 1.7.x-issue4257 branch:

 * ^/subversion/branches/1.7.x-issue4257
   Fix issue #4257 ("neon get_dir leads to bogus NODES rows").
   Justification:
     Bug can tigger assertions in the WCDB code.
   Branch:
     ^/subversion/branches/1.7.x-issue4257
   Notes:
     While not strictly related to this issue, svn_ra_neon__do_stat()
     could probably stand to have the same patch applied as
     svn_ra_neon__get_dir(), as this pattern of using full URLs
     was found to be troublesome in issue #4332's research, too.
