Deprecated. When `ext_cmdline` and `ext_popupmenu` are both set,
|ui-popupmenu| events will be used for command-line completion. But if
`ext_wildmenu` is also set, these events are still used for backwards
compatibility. New clients should use `ext_popupmenu` instead.
["wildmenu_show", items]
Activate the wildmenu (command-line completion). `items` is an array
with the completion items.
["wildmenu_select", selected]
Select an item in the current wildmenu. `selected` is a zero-based
index into the array of items from the last wildmenu_show event, or -1
if no item is selected.
