SA Bugzilla – Bug 7796
body_part_scan_size is documented as a user preference, not an admin setting

In revision r1872864 from the 3.4 branch, the settings 'body_part_scan_size' and 'rawbody_part_scan_size' have been turned into administrator settings. However in the documentation, they are still listed under the 'USER PREFERENCES' section instead of the 'ADMINISTRATOR SETTINGS' section. The same problem is in the trunk branch as far as I can tell.
fixed in r1874343.
