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.
