### Please describe the problem.

Complained elsewhere (http://git-annex.branchable.com/bugs/inconsistent_output_upon_addurl_--batch_complicates_if_not_forbids_reliable_parsing_of_output/) haven't mentioned it was marked fixed, so reiterating as independent bugreport

With today's version
[[!format sh """

$> echo "http://www.onerussian.com/tmp/banner.png 123" | git annex addurl --batch --with-files
addurl 123 git-annex: 123 already exists and is not annexed; not overwriting                  

$> echo "http://www.onerussian.com/tmp/banner.png 123" | git annex addurl --batch --with-files 2>/dev/null
addurl 123 %       

$> echo "http://www.onerussian.com/tmp/banner.png 123" | git annex addurl --batch --with-files --json 2>/dev/null 
{"command":"addurl","file":"123"%
