+Enhancement: Support `<snapshot>:<subfolder>` syntax to select subfolders
+
+Commands like `diff` or `restore` always worked with the full snapshot. This
+did not allow comparing only a specific subfolder or only restoring that folder
+(`restore --include subfolder` limits the restored files, but still creates the
+directories included in `subfolder`).
+
+The commands `diff`, `dump`, `ls`, `restore` now support the
+`<snapshot>:<subfolder>` syntax, where `snapshot` is the ID of a snapshot or
+`latest` and `subfolder` is a path within the snapshot. The commands will then
+only work with the specified path of the snapshot. The `subfolder` must be a
+path to a folder as returned by `ls`. 
+
+`restic restore -t target latest:/some/path`
+`restic diff 12345678:/some/path 90abcef:/some/path`
+
+For debugging purposes, the `cat` command now supports `cat tree
+<snapshot>:<subfolder>` to return the directory metadata for the given
+subfolder.
