This removes make_command_stats_cleanup in favor of an RAII class. The patch is reasonably straightforward, but keeping the same semantics without excessive reindentation required splitting captured_main in two. 2016-10-21 Tom Tromey <tom@tromey.com> * maint.h (scoped_command_stats): New class. (make_command_stats_cleanup): Don't declare. * maint.c (struct cmd_stats): Remove. (~scoped_command_stats): Rename from report_command_stats. Now a destructor. (scoped_command_stats): Rename from make_command_stats_cleanup. Now a constructor. * main.c (captured_main_1): New function. Use scoped_command_stats. (captured_main): Call captured_main_1. * event-top.c (command_handler): Use scoped_command_stats.
