Documentation
Sort candidates in the *Completions* buffer.
Completion candidates in the *Completions* buffer are sorted depending on the value.
If it's nil, sorting is disabled.
If it's the symbol alphabetical, candidates are sorted by
minibuffer-sort-alphabetically.
If it's the symbol historical, candidates are sorted by
minibuffer-sort-by-history, which first sorts alphabetically,
and then rearranges the order according to the order of the
candidates in the minibuffer history.
If it's a function, the function is called to sort the candidates.
The sorting function takes a list of completion candidate
strings, which it may modify; it should return a sorted list,
which may be the same.
If the completion-specific metadata provides a
display-sort-function, that function overrides the value of
this variable.
This variable was added, or its default value changed, in Emacs 30.1.
Probably introduced at or before Emacs version 29.1.
