    Bug 24791
    
    The tests for temporary tables have been fixed. Since the call to 
    display_length(Item) was removed from the constructor for Item_type_holder, items 
    in temporary tables keep the original values of the items, rather than the magic
    numbers supplied by display_length.

# This is a BitKeeper patch.  What follows are the unified diffs for the
# set of deltas contained in the patch.  The rest of the patch, the part
# that BitKeeper cares about, is below these diffs.
