I'm not sure if `vc-hooks.el' changed since 20.4. In its 20.4 version, there was code that said: ;;;###autoload (define-key global-map "\C-x\C-q" 'vc-toggle-read-only) This is evil, because the file is loaded at run-time, when it overrides the user's setting for `C-x C-q'. The right way to do it is like this: ;;;###autoload (define-key global-map "\C-x\C-q" 'vc-toggle-read-only) That way, the autoloads will contain the correct keydef, which will be overridable by the user's init file. Could someone with the convenient access to the latest package tree make the patch? Thanks.
