* Fix block scoping error if an explicit block is broken by twoIngo Schwarze2017-02-161-5/+14
| | | | | | | | | 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.
* Finally port the OpenBSD regression suite.Ingo Schwarze2017-02-081-0/+32
Both kristaps@ and wiz@ repeated asked for this, literally for years.
