It would be nice to have git annex unused report the total size of unused files.

I tried:

• ❌ git annex unused: doesn't show the size
• ❌ git annex info: doesn't list unused size
• ❌ git annex info --unused: doesn't work
• ❌ git annex list --unused: doesn't work
• ❌ git annex find --unused: doesn't work

Maybe I'm missing something, but it feels like having git annex unused and git annex info directly report it would be nice.

Cheers, Yann
