usr.bin/mandoc : mdoc_macro.c
Log message:
For child macros of block-end macros, only scan backwards for pending
breakers unless the parent of the block is already closed. While
the scanning is needed in cases like ".Ac Bo" for broken Ao, it is
useless and crashy in cases like ".Ac Bc" for non-broken Ao.
This fixes a NULL pointer dereference that tb@ found with afl(1).
