### Please describe the problem.
If there are staged changes in two files (one in git, one in annex) and I want to commit them by explicitly giving git-commit both paths (in order to exclude other changes that are possibly staged), the not annexed file stays staged, while committing everything staged by not giving any path to git-commit works just fine.

### What steps will reproduce the problem?
[[!format sh """
mkdir testv6
cd testv6
git init
git annex init --version=6
echo some > file_in_git
git -c annex.largefiles=nothing annex add file_in_git
echo more > file_in_annex
git annex add file_in_annex
git commit -m "files added" file_in_git file_in_annex
git status

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
