Controlling INPUT ARRAY temporary row creation

Down move after last row in INPUT ARRAY creates a new temporary row.

The INPUT ARRAY dialog and sub-dialog provides the APPEND ROW and AUTO APPEND attributes to control row creation at the end of a list (known as temporary row creation).

APPEND ROW controls explicit temporary row creation, while AUTO APPEND controls automatic temporary row creation.

Starting with version 2.20, moving down after the last row (with the mouse or keyboard) or leaving the last column of the last row with a TAB key are considered events that trigger automatic temporary row creation.

Before version 2.20, these cases were considered as events for an explicit temporary row creation. In other words, if you want to deny temporary row creation in such case, it is now done with AUTO APPEND = FALSE while in older versions it was controlled by APPEND ROW = FALSE.
