Use ', not #', when a given symbol may not have a function binding at read time 2011-03-10 Aidan Kehoe <kehoea@parhasard.net> * cmdloop.el (yes-or-no-p): * cmdloop.el (y-or-n-p): * descr-text.el (describe-char): * diagnose.el (show-memory-usage): * diagnose.el (show-object-memory-usage-stats): * diagnose.el (show-mc-alloc-memory-usage): * diagnose.el (show-gc-stats): * faces.el (face-font-instance): * gtk-font-menu.el (gtk-reset-device-font-menus): * help.el (help-symbol-function-context-menu): * help.el (help-symbol-variable-context-menu): * help.el (help-symbol-function-and-variable-context-menu): * help.el (help-find-source-or-scroll-up): * help.el (help-mouse-find-source-or-track): * help.el (temp-buffer-resize-mode): * minibuf.el (mouse-read-file-name-1): * obsolete.el (find-non-ascii-charset-string): * obsolete.el (find-non-ascii-charset-region): * occur.el (occur-engine): * paragraphs.el (forward-paragraph): * paragraphs.el (forward-sentence): * select.el (activate-region-as-selection): * select.el (select-make-extent-for-selection): * simple.el (zmacs-make-extent-for-region): Use quote, not function, for quoting symbols that may not be fboundp at the point they are read (again, a style issue, since Common Lisp throws an error on this, but we don't, and have no plans to.)
