Re: dired-copy-preserve-time affects file modes, too.

[Richard Stallman]

    The last sentence of the docstring for copy-file says

      Also set the file modes of the target file to match the source file.

Now I understand.  Thanks.

    The variable dired-copy-preserve-time toggles the behavior of
    dired-do-copy and it also affects the prompt when dired-do-copy is
    called interactively. If dired-copy-preserve-time is nil the prompt
    says "Copy". If it is non-nil, the prompt says "Copy [-p]".
    However, the info page from GNU Coreutils says about the options of
    the command cp

It is harder to see the right way to clarify that one.
