Fix block scoping error if an explicit block is broken by two
implicit blocks (.Aq Bq Po .Pc) that left the outer breaker open
and could in exceptional cases, like between .Bl and .It, cause
tree corruption leading to NULL dereference.
Found by tb@ with afl(1).
While here, do not mark intermediate ENDBODY markers as broken.
