I believe this is expected behavior.  I mentioned it in the patch I submitted 
and no one complained, at least.  If you're taking the "compare" approach, 
you could use that immediate-return behavior to "prime the pump" by 
immediately storing the current contents so that you'll later have something 
to compare against.

Hope that helps.
