"Sort function to use for choosing a completion candidate to preview.
Completion Preview mode calls the function that this option specifies to
sort completion candidates. The function takes one argument, the list
of candidates, and returns the list sorted.
The default sort function sorts first by length, then alphabetically.
To disable sorting, set this option to `identity'.
If the completion table that produces the candidates already specifies a
sort function, it takes precedence over this option."
