acl 6.x-1.2

This is version 1.2 of ACL for Drupal 6.

Version 1.0 has been working very solidly with the exception of a minor glitch when updating from Drupal 5. The reason for releasing 1.1 was to provide a defined base for starting the migration to Drupal 7.

Unfortunately, the fix was not perfect and had the potential to produce a harmless warning message. 1.2 avoids that warning message.

Changes since 1.0:
Enhancements:
- Clean up some minor coder issues (no functional changes).
Bugs fixed:
- #694236: Suppress a harmless but irritating warning from acl_update_6001(), introduced in the #680324 fix.
- #680324: Add missing index if upgraded from D5.

Note: The devel_node_access (DNA) module, which is part of the Devel module, provides an in-depth view into the inner workings of node access, especially if you enable its debug mode at admin/settings/devel#edit-devel-node-access-debug-mode and its second block. This is a big help for understanding the forces that control access to any given node.

Note the Drupal core issues listed on the ACL front page, which are outside the scope of ACL. Help resolve these issues to make ACL perform even better!
