+Normally, the display of completions which don't fit on the screen is
+controlled by the LISTMAX parameter (currently ${LISTMAX:-unset}), which
+specifies the maximum number to show without asking.  Instead, you can make
+completion lists scroll when they don't fit on the screen.  To do this,
+edit a prompt to show when scrolling is active; an empty string turns
+this feature off.  It can contain \`%l' to show the number of matches
+as \`current_number/total_number', as well as font-control sequences such
