The version 0.9 (or 20120505.1234 from MELPA) doesn't work for me. In some files (e.g. outline-magic.el itself), when the point is at the beginning of the buffer and I run `outline-cycle', the whole buffer gets hidden. Subsequent runs of `outline-cycle' fail and everything remains hidden. The failure is caused by (error "before first heading") called from `outline-back-to-heading`.

I run GNU Emacs 24.3.1 (x86_64-pc-linux-gnu, GTK+ Version 3.4.2) of 2013-04-13 on trouble, modified by Debian.

This patch fixes the problem.
