Subject: 24.0.90; dired/copying+dwim-target : misplaced directory 
Date: Mon, 24 Oct 2011 23:12:41 +0200

Create some directories :

$ find 
dest
dest/a
source
source/a
source/a/foo

Open two dired buffers in source + dest, enable `dired-dwim-target' and
dired-do-copy source/a to dest.  Now dest looks like this :

/tmp/dest
/tmp/dest/a
/tmp/dest/a/a
/tmp/dest/a/a/foo

It's unclear what do you expect.  If you want to get this:

/tmp/dest
/tmp/dest/a
/tmp/dest/a/foo

then you have to remove the final slash in the minibuffer
after calling `dired-do-copy'.  So instead of:

  Copy a to: /home/work/emacs/test/dired-dwim/dest/ RET

you rather need this:

  Copy a to: /home/work/emacs/test/dired-dwim/dest RET

and then it will ask:

  Overwrite `/tmp/dest/a'? [Type yn!q or C-h] n

and then it's better to answer `n'.

The current behavior is wrong.  I see 3 valid outcomes:

    /tmp/dest
    /tmp/dest/a
    /tmp/dest/a/foo
or
    /tmp/dest
    /tmp/dest/a
    /tmp/dest/foo
or
    an error message or a prompt about the overwrite.

That's counter intuitive: I'd expect either the terminating slash to be
of no consequence or else I'd expect "...dired-dwim/dest" to result in
the second option (i.e. copy the content of "source/a" into "dest") and
"...dired-dwim/dest" to result in the first option (i.e. copy the
contents of "source/a" into "dest/a").

I expect it to work like 'cp -r', Stefans first outcome.  This is also how it
is (more or less) advertised in the info-manual (info "(emacs) Operating on
Files") .
