If nil, `load' and `read' raise errors when encountering some
old-style variants of backquote and comma. If non-nil, these
constructs are always interpreted as described in the Info node
-`(elisp)Backquotes', even if that interpretation is incompatible with
+`(elisp)Backquote', even if that interpretation is incompatible with
previous versions of Emacs. Setting this variable to non-nil makes
Emacs compatible with the behavior planned for Emacs 28. In Emacs 28,
this variable will become obsolete. */);
