I wrote my previous reply before reading the rest of the thread. I assumed 
that someone else (especially Adam, who usually is a stickler for such 
things) had already provided the right answer. I feel better that I didn't 
remember it after seeing that no one else even found it!

Note that A.16(123/2) is a "shall" rule; there is nothing optional about it. 
Why we didn't just put it into the description of Copy_File isn't clear, but 
the rule surely exists.

The AARM provides a reason for the rule: "This means that Copy_File will 
copy any file that the Ada programmer could copy (by writing some possibly 
complicated Ada code)."
