* ui: restore --delete indicates number of deleted files
* adds new field `FilesDeleted` to the State struct, JSON and text progress updaters
* increment FilesDeleted count when ReportedDeletedFile
* ui: collect the files to be deleted, delete, then update the count post deletion
* docs: update scripting output fields for restore command
ui: report deleted directories and refactor function name to ReportDeletion
This keeps backwards compatibility with the previous empty structs.
And maybe we'd want to put other fields into the inner struct later,
rather than the outer message.
In order to evaluate the keep reasons for snapshots, there should be also the id's
to compare it with snapshots within the keep object. (See also Issue #3117)
In order to avoid output parameters also changed function addJSONSnapshots to asJSONSnapshots
This introduces a new modifier to the output of the diff command. It
appears whenever two files being compared only differ in their content
but not in their metadata. As far as we know, under normal
circumstances, this should only ever happen if some kind of bitrot has
happened in the source file. The prerequisite for this detection to work
is that the right-side snapshot of the comparison has been created with
"backup --force".
This introduces the inode attribute to the JSON output emitted for nodes
in `ls` and matches in `find`. There doesn't seem to be any discernible
reason to omit the inode and it can be useful in scripting scenarios.
