-
-  Possible string values are:
-    - `"none"`:   Doesn't inform anything about hidden files.
-    - `"simple"`: Shows how many hidden files are in a folder.
-    - `"all"`:    Shows how many files are hidden and the number of hidden
-                files per reason why they're hidden.
-
-  Example `"all"`:
-    If a folder has 14 hidden items for various reasons, the display might
-    show: >
-    (14 total git: 5, dotfile: 9)
-<
-  If a function is provided, it receives a table `hidden_stats` where keys are
-  reasons and values are the count of hidden files for that reason.
