* Non-maintainer upload. * Fix "removes files that were installed by another package": don't remove directories that are owned by (and removed from) nginx-common from nginx-extras.postrm. This seems to have been the idea in commit e30a854 ("Moved configuration purging to nginx-common.") except that it was added in nginx-common.postrm without being removed in nginx-extras.postrm. Remove nginx-extras.postrm since it's empty after this change. (Closes: #681758)
