master 5a1785d: Sort Info index completions alphabetically

[Stefan Kangas]

branch: master
commit 5a1785d58ad807cb8e4af6903313b1c6b49cf572

    Sort Info index completions alphabetically
    
    * lisp/info.el (Info-complete-menu-item): Sort the list of completions
    alphabetically using 'nreverse'.  This makes no difference for Emacs
    but helps third-party completion frameworks such as Ivy.  (Bug#38614)
