Ok, let me try again:

   ifšiteratoršisšalsošašmodelšofšthešreadablešiteratoršconcept,šthen
šššexpressionš*rv should be equal to *v, where v is the value of iterator
   before call to operator++(int) and rv is the value returned from the
   call.

The good question is what 'equal' means? Operator== might not be defined.
The standard uses 'equivalent' but I don't know what that means.
