### Please describe the problem.

Even if  -c annex.largefiles=nothing  is used with git add, then git commit  commits file into annex.

This script demonstrates initial finding: http://www.onerussian.com/tmp/ga.sh

Even if we use -c annex.largefiles=nothing  with both add and commit, subsequent   git status   migrates that file into annex (which is even more weird)

Adjusted script demonstrates it: http://www.onerussian.com/tmp/ga-2.sh

### What steps will reproduce the problem?

see above

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

6.20170101+gitg93d69b1-1~ndall+1


### Please provide any additional information below.

For completeness here is the output of the 2nd script run:
