[erlang-bugs] Copying a file to itself

[John Hughes]

Calling file:copy(Name,Name) to copy a file to itself truncates the file to
0 bytes. I'm not sure if this is a bug, but it isn't what I expected-even
after reading the documentation. Perhaps either file:copy should return an
error in this case, or the documentation should mention this behaviour
explicitly.
