This adds a variable which keeps track of the previous saved search
results. It is stored as a plist with keys being the saved
searches. The result the saved search display function gave last time
is passed to the display-function as the the keyword :old argument.
This is useful for display functions that want to keep some state: eg
to show that the count has changed, new messages have arrived etc. The
function returns a saved search style plist so it can store any
information it likes inside this plist.
