bug#44067: 27.1; Inconsistency between Emacs and Elisp manuals

[immanuel]

ELisp manual says:
" If this second dir-locals file is present, then that is loaded instead of
 ‘.dir-locals.el’."

Emacs manual says:
" You can also use ‘.dir-locals-2.el’; if found, Emacs loads it in
addition to ‘.dir-locals.el’."



In GNU Emacs 27.1 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.22.30, cairo 
version 1.15.10)
 of 2020-08-24 built on prometheus
