If I block an account on test.wikipedia.org that has no user page, the block does not show up in Special:Watchlist. The block will not appear on Special:Watchlist regardless of whether I later add the user's user page to my watchlist or if I select the "watch this user's page" checkbox during the block submission.
If I create the user page after the account has been blocked, the block _still_ does not appear at Special:Watchlist. This may be a separate bug.
If the user page already exists when I block the account, I can watch or unwatch the user page at my discretion and the relevant block entry will appear at Special:Watchlist depending on whether I'm watching the user's user page. (This is the correct behavior.)
