git-annex/doc/bugs/addurl_failure_has_empty_error-messages.mdwn

While running `git-annex addurl --batch --with-files --jobs 10 --json --json-error-messages --json-progress --raw`, I occasionally run into files that fail to download for no discernable reason, and the `"error-messages"` key in the output from the command is an empty list.  This makes it hard to figure out exactly why the download is failing.

fix addurl concurrency issue addurl: Support adding the same url to multiple files at the same time when using -J with --batch --with-files. Implementation was easier than expected, was able to reuse OnlyActionOn. While it will download the url's content multiple times, that seems like the best thing to do; see my comment for why.
