+    This field handles the configuration for prompt history.

+      - limit:   The amount of entries that will be written in the
+                 history.
+                 Warning: If limit is set to nil it will grown unbound.
+                 default: 100
+      - handler: A lua function that implements the history.
+                 This is meant as a developer setting for extensions to
+                 override the history handling, e.g.,
+                 https://github.com/nvim-telescope/telescope-smart-history.nvim,
