	* glib/gspawn-win32.c (do_spawn_with_pipes): Do handle
	G_SPAWN_DO_NOT_REAP_CHILD after all, similarily as on Unix. If the
	flag is not set, don't call DuplicateHandle() on the handle
	returned by the helper process, and set the "child pid"	returned
	to the caller to zero. Close the handle to the helper process in
	all cases.

	* glib/gspawn.c (g_spawn_async_with_pipes): Document Windows
	behaviour of G_SPAWN_DO_NOT_REAP_CHILD.
