Advanced Rogue 5, 7: fix some trading post messages. When attempting to buy an unaffordable object, messages were often of the form "You can't afford that a scroll of hold monster !", because the object description (stored in curpurch) was the same text used in inventory displays. This has been worked around by inspecting the contents of curpurch and using different message templates.
