Subject: 25.1; diff with DIRED error

Hi,

        When using diff with dired I am getting an error:

0. emacs -Q &

1. C-x d RET

2. m (dired-mark)
   mark two files, file.txt file.txt~

3. C-p C-p (dired-previous-line)
   move to line with file.txt

4. Click Immediate->diff

5. Click Open for file.txt~


   I then get the following *Diff* buffer with errors:

diff -u /home/liveuser/file.txt\~ /home/liveuser/file.txt
--- /home/liveuser/file.txt~	2017-03-15 08:23:58.796074954 -0400

Diff finished.  Mon Mar 27 17:14:10 2017


[Aside;  Why are the diff files reversed?

         Why isn't the diff command:

diff -u /home/liveuser/file.txt /home/liveuser/file.txt\~

         Is there any way to get "diff -u file.txt file.txt~",
         i.e. the file that is clicked on (step 5 above) is
         the second file, not the first in the diff -u command?]


         Thanks.

I can't reproduce this.
If it still happens with current Emacs, please send backtrace after
M-x toggle-debug-on-error.
