git-annex/doc/todo/add_--json-progress_to_fsck_--json.mdwn

Please add the feature/switch `--json-progress` to `git annex fsck --json`.

For a basic version, it would be nice to show the percentage using the number of processed chunks / total number of chunks for a given file while calculating checksum.

Let's not forget that a file on a remote can be fsck-ed when using `--from <remote>`. In this case if the file is not present locally, the file must be downloaded first (`--json-progress` is already supported for `get`). Usually this takes much-much longer as the checksum calculation. When checking a large file (~1Gb) on a not too fast remote, it's quite a time for the first "response" that something is happening when using the `--json` switch. To be exact, the first and only response is that the check has finished (happy way). It would be nice to see the json progress of the download+checksum calculation.
