5d477a334a (fsck (receive-pack): allow demoting errors to warnings,
2015-06-22) allowed a list of fsck msg to downgrade to be passed to
--strict. However this is a hidden argument that was not documented nor
tested. Though it is true that most users would not call this option
directly, (nor use index-pack for that matter) it is still useful to
document and test this feature.
