- References: <cover dot 1368124285 dot git dot tromey at redhat dot com>
This fixes some of the problems in infrun.c that the checker reported.
I filed the remaining problems as bugs.
This patch is purely stylistic.
* infrun.c (handle_vfork_child_exec_or_exit)
(fetch_inferior_event, adjust_pc_after_break): Introduce
an outer null cleanup.
