Please update app-emacs/folding to newest version or provide a 9999 GIT/SVN access to newest version at http://git.savannah.gnu.org/cgit/emacs-tiny-tools.git/tree/lisp/other/folding.el When installing current version, we get lots of warnings like folding.el:2671:5:Warning: `error' called with 1 args to fill 0 format field(s) In folding-is-hooked: folding.el:2702:39:Warning: `write-file-hooks' is an obsolete variable (as of 22.1); use `write-file-functions' instead. folding.el:2703:39:Warning: `find-file-hooks' is an obsolete variable (as of 22.1); use `find-file-hook' instead.
