1. Enable dired-dwim-target and fido-mode
(custom-set-varibles
'(dired-dwim-target t)
'(fido-mode t))

2. Create two diretory trees, with following layout:

source_tree
source_tree/a.txt
source_tree/b.txt
source_tree/c.txt

destin_tree/d.txt

3. Open two root diretory, with dired-mode, in two windows side by
side. For dired-twim-target to work.

4. Mark, a.txt, b.txt, c.txt in source_tree.

5. Type `C` and `dired-twim-target` will prompt to to copy them to
destin_tree

6. Type `Enter` to confirm.

7. Copy report an error, say that target must be a directory instead of
`d.txt`.


The expected behavior is: 3 files successfully copied to destin_tree.

A known Workaournd is: Type `.` before step 6, to make sure dired
selected the target directory itself, instead of something inside it.

This is inaccurate: at this point I see the following in the
minibuffer:

  Copy * [3 files] to: .../dest_tree/{d.txt | ./}

Obviously, "d.txt" is an incorrect guess, and what I actually want is
the second guess, "./".  So I type <RIGHT> arrow key, and that makes
"./" the selected candidate.

> 6. Type `Enter` to confirm.

After making "./" the selected candidate, this "does what I mean".

So I think Emacs works as expected here.  We cannot always expect
Emacs to guess what you mean with 100% accuracy.

No further comments within 3 weeks, so I'm closing this bug.
