The Janus/Ada implementation of Ada.Directories has the following change 
note:

  Corrected Copy_File to overwrite existing files, as A.16(123/2) makes it 
clear that it should work the same as Create (which can overwrite existing 
files).

which points to the paragraph that answers your question.

(Which is another way of saying that I didn't remember the answer to this 
until I happened across that note. And that is annoying since this package 
was originally my design and mostly was worded by me. Sad to think I've 
already forgotten about it...I fear my wetware needs a RAM upgrade!)
