[ale] Ghost SGID on extract?

[Leam Hall]

Okay, I've never seen this before.

1. tar.gz file built by root, permissions do not include SGID flag on base directories.
2. Extract as user, no problem on multiple OS (Linux, Mac) versions.
3. Extract as root, some of the directories are SGID.
4. Extract the same tar.gz file over the first extraction, and the dirs are no longer SGID.

What could cause this?
