When a block using the new block types ('Block anonymous users only' and
'Prevent account creation') is made, the entry in Special:Ipblocklist is made in
blocked <USER/IP> (contribs) (expires <DATE>, <account creation blocked or anon.
However, block log entries are made without the block type. It shows the length,
blocker, and blockee, but does not show if the account creation or anon only
statuses are set.
