bug#10489: 24.0.92; dired-do-copy may create infinite directory hierarchy

[Stefan Monnier]

> Maybe we could change the entry in files.texi like this:
[...]
>   @defun file-equal-p file1 file2
>   This function returns @code{t} if the files @var{file1} and
> ! @var{file2} name the same file.  If @var{file1} or @var{file2} does
> ! not exist, the return value is unspecified.

That looks good.

> ! If two files are equal, it does not imply that both file names specify
> ! accessible files.  For example, @file{/sudo::/foo/bar} might be
> ! accessible, but @file{file:///foo/bar} might not.  (@pxref{Remote
> ! Files,, Remote Files, emacs, The GNU Emacs Manual}, and
> ! @pxref{Supported URL Types,, Supported URL Types, url, URL
> ! Programmer's Manual})

I'd rather not get into such issues in the doc.
