From 13634dec038d613c3b618d70cd64d6d63561f2eb Mon Sep 17 00:00:00 2001 From: Artur Malabarba Date: Mon, 13 Apr 2015 13:13:36 +0100 Subject: [PATCH] * lisp/emacs-lisp/cl-macs.el (cl-defstruct): Implement docstrings Adding a string after a constructor's argument list will use that string as the constructor function docstring. If this string is absent but the struct itself was given a docstring, use that as the constructor's docstring.
