From 1756e4757cee336defa4aea667d0e991737f562c Mon Sep 17 00:00:00 2001 From: Lars Ingebrigtsen Date: Tue, 15 Jun 2021 15:33:03 +0200 Subject: [PATCH] Fix false positives in docstring width warning with (fn...) constructs. * lisp/emacs-lisp/bytecomp.el (byte-compile--wide-docstring-p): Don't consider the function signature when determining whether the doc string is too wide (bug#49007).
