`--all` would make git-annex operate on either every key with content present (or in some cases like `get` and `copy --from` on every keys with content not present). This would be useful when a repository has a history with deleted files whose content you want to keep (so you're not using `dropunused`). Or when you have a lot of branches and just want to be able to fsck every file referenced in any branch. It could also be useful (or even a good default) in a bare repository. A problem with the idea is that `.gitattributes` values for keys not currently in the tree would not be available (without horrific anounts of grubbing thru history to find where/when the key used to exist). So `numcopies` set via `.gitattributes` would not work. This would be a particular problem for `drop` and for `--auto`. --[[Joey]]
