Freeing room direction

From: John (witpens@optushome.com.au)

Once I free all the strings involved in world[i].dir_option[j] (ie.
general_description and keyword), is it ok for me to set
world[i].dir_option[j] = NULL;
Why I ask this is because when I
free(world[i].dir_option[j]);
The memory is freed, but the exit shows up in autoexit and when you
actually go in that direction, it crashes the mud.

It works fine if I set it to NULL but I fear I havent really cleared the
memory (is this a memory leak here?)

Thanks :)
