I keep a database file in git-annex so it stays synced across several machines. My wrapper when accessing it is basically

git annex sync --content
git annex unlock $database
[access database]
git annex add $database
git annex sync --content

This works fine except it creates an entry in the log for the database file even if that stays unchanged. I would like an option that just returns to the state before git annex unlock if the file has not been changed. Maybe git annex add --restore-unchanged?

done --Joey
