Description:
------------
Copying a file into itself causes the source file to be truncate to 0
bytes.
copy("test", "test"); // test.txt -> 0
You can't avoid this problem just by comparing the filenames, since one
could be a symlink pointing to the other. The following would destroy
test1 if test2 is a link to test1:
copy("test1", "test2");
Reproduce code:
---------------
copy("test", "test");
Expected result:
----------------
Nothing happens or a file open error.
Actual result:
--------------
Contents in source file is lost.
