I want to see aggregate stats on all keys known to git-annex while using matching options like --in here, --copies etc.

The obvious thing I tried was to use git annex info --in here but that complains:

git-annex: File matching options can only be used when getting info on a directory.

There should be a way to use info to query aggregate information properties of all keys instead of directories.

I have used git annex info . in the repos I used up until now because every key was in the tree. Though I also have a feeling that operating on all keys could be significantly faster than filtering them to match some directory.
