- Patch #38999 by saerdna: There's no need that users with the "administer comments" role has to go via admin/comments to delete comments. this patch simply adds the delete link on each comment if you have administer comments role.  "access administration pages" not needed; because if they not have it they can still delete from admin/comments.

- Minor code simplifications in search_parse_query()

  Changed code to be compatible with all versions.

- Patch #40886 by chx: fixed problem with recursive/nested node API calls manipulating the same array references.
