* child_info.h (child_status): Fix typo which made it impossible to set 

iscygwin.
(child_info::isstraced): Booleanize.
(child_info::iscygwin): Ditto.
* sigproc.cc (child_info::child_info): Minor cleanup of flag setting.
* spawn.cc (spawn_guts): Only close_all_files when we know the process has
started successfully.
* exceptions.cc (init_console_handler): Fix indentation.
