Function set_unique_inventory:
Defined in module m_vendor (file: /std/modules/m_vendor.c)

void set_unique_inventory(string str)
This function determines if the vendor should hold onto what he
buys instead of desting it and replacing it with an original.  For
Example without unique set if you sell a sword to the vendor, no
matter what the condition is, it will be dested and replaced with
a new one.  Some muds would prefer the old way of what you sell is
what you buy.  The unique inventory is set by sending the room
where the inventory is kept.
ex: set_unique_inventory("/domains/std/rooms/storage");
NOTE: only armor, weaps, vehicles are uniqued
Unless the object has a is_unique() { return 1; } function in it
See set_all_unique to unique everything
