If we unhide B, we don't know that it was landed.

We can restore it by re-introducing the links via mutation records.  This is a temporary
hack until we write an indexed changelog that lets us do the successor lookup for any
commit cheaply.  Normally the pullcreatemarkers and pushrebase extensions will do this
for us, but for this test we do it manually.

  $ hg debugsh --hidden -c "with repo.lock(): m.mutation.recordentries(repo, [m.mutation.createsyntheticentry(repo, [repo[\"$C\"].node()], repo[\"$X\"].node(), \"land\")], skipexisting=False)"
