A function or macro body consisting of a single string literal now only uses it as a return value. Previously, it had the dual uses as return value and doc string, which was never what the programmer wanted and had some inconvenient consequences (bug#69387). This change applies to `lambda`, `defun`, `defsubst` and `defmacro` forms; most other defining forms already worked in the sensible way. * lisp/emacs-lisp/bytecomp.el (byte-compile-lambda): Don't use a lone string literal as doc string. * test/lisp/emacs-lisp/bytecomp-resources/warn-wide-docstring-defun.el (foo): Update docstring warning test. * doc/lispref/functions.texi (Function Documentation): Update. * etc/NEWS: Announce. |
