It should become a generic mechanism that would allows one to truncate a string so that fits in N possibly truncated screen lines of a full-width window. * lisp/emacs-lisp/eldoc.el (eldoc-handle-docs): Tweak --- diff --git a/lisp/emacs-lisp/eldoc.el b/lisp/emacs-lisp/eldoc.el index 9efd770dca6..24b6ceca48a 100644 --- a/lisp/emacs-lisp/eldoc.el +++ b/lisp/emacs-lisp/eldoc.el @@ -479,7 +479,7 @@ Honor most of `eldoc-echo-area-use-multiline-p'."
