Isn't this second-guessing what the user means?  What if the kill ring
has "/foo/bar/" and the user wants to append a file name to that, thus
creating a valid absolute file name?

Thanks.

Maybe, but not so standard way; we can skip that part of the fix, though.
The command provide a nice way to do that as mentioned in the doc string:
C-u 0 w

Sorry, I don't understand: which part of the fix you suggest to skip,
and what will be left then?

No, that produces the absolute names of files in the directory shown
by Dired, whereas what I meant is constructing a name of a file in
another directory by concatenating a directory killed in another kill
command and the file name killed by 'w'.

Agreed.  It might be useful.

So, the patch now fix the II) in the report: it prevent to change the kill
ring when the string is empty.
The command name and the doc string suggest the usage is about copying
file names.
I would prefer if this command have effect just when point is:

1) on a line showing a subdir name
for instance:
(dired-subdir-min)

2) on a line showing a file from the dired listing
on a line displaying a file or subddir name
for instance,
(progn (goto-char (dired-subdir-min)) (dired-goto-next-file) (point))

Currently the command is enabled whatever is the point in the Dired 
buffer.  As a consequence, the command put a "" in the kill ring if
the command is called with the point in one position other than 1) 2)
for instance:
3)
(progn (goto-char (dired-subdir-min)) (forward-line 1) (point))

I would propose in order of preference:

A) Do not change the kill ring when the command is called with point
    in a position like 3) (See patch below).
B) Update the doc string alerting that the command is responsive even
    if there is no filename/subdir accesible: the kill ring will get "" in
    that cases.

That should be fine, thanks.

Thanks.  Two minor comments:

 . When you close a bug, please reply to the last message related to
   that bug, so that the Subject line is meaningful (as opposed to the
   above).

 . Please try making the summary line of the commit log message be as
   specific as possible, within the limitations of 64 characters.  The
   one you used here:

      Copy just non-empty strings to kill-ring

   is too general: it fails to mention Dired.  I would suggest
   something like this:

      Avoid copying empty strings with Dired's 'w' command

Thanks.
