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.
