This avoids a later git status or similar taking a long time to run as it runs git-annex smudge once per file. While v9 repositories do avoid that taking long when the files are small, large files can still make git status take a very long time. This does make unlock slower, because now git-annex smudge is being run once per file unlocked. However, the next commit should speed that up in many cases.
