Re: Dangerous behavior when copying to current directory

Your fix works only for the case where a specified directory has no
final slash.  But after invoking M-x copy-file or M-x rename-file
the default initial value for the second argument has a final slash,
e.g. `/tmp/'.  Since `copy-file' and `rename-file' have interactive
specification `F' for the second argument, when they get called with
the default value after typing RET, the second argument is already
expanded to the wrong file name.  The culprit is the function
`read-file-name' which always adds the current buffer name to the
returned value when a directory name was specified by the user.

So the danger of overwriting files with `copy-file' and other similar
commands still exists.
