### Please describe the problem.

When addurl'ing a big file with .gitattributes configured to add only some files directly into git (and 'git annex add' operating correctly), addurl adds large files straight into git.

### What version of git-annex are you using? On what operating system?

git-annex version: 6.20161018+gitgf3c366a-1~ndall+1


### Please provide any additional information below.
