Just provide a list of default values (strings) as argument
DEFAULT to `completing-read', `read-string', or similar.
`C-h f read-string':
Fourth arg DEFAULT-VALUE is the default value or the list of default values.
If non-nil, it is used for history commands, and as the value (or the first
element of the list of default values) to return if the user enters the
empty string.
