I suppose that there might be some circumstances where the existing behaviour 
is preferable.  There are lots of ways in which "xargs -0" is different to the 
default behaviour, so I don't see analogy with the default behaviour as being a 
convincing argument that the behaviour of -0 should change.  Is there some 
other reason for doing this that I'm missing?

Summary:  make -0 skip redundant delimiters (like default mode)

Original Submission:  xargs doesn't ignore "empty" arguments when -0 used
(I.E. when '' is the delimiter).

This illustrates the erroneous difference
fixed by the patch

$ echo -ne "1nnn2" | xargs -n1 | od -t x1
   0000000 31 0a 32 0a
$ echo -ne "10000002" | xargs -0 -n1 | od -t x1
   0000000 31 0a 0a 0a 32 0a

As you can see the first command works as expected,
whereas the second doesn't.

In summary multiple consequtive ''s should be squeezed
to 1 ''

Is there not enough info in my previous comment?

the output from the 2 commands should be the same.
With the patch the second command outputs the same
as the first.

Could you privide a test case that demonstrates the problem that this bugfix 
actually fixes?
