I previously reported this but without the word "bug" in my subject
line. My mistake.
When my cursor is on an 'in buffer setting' line
#+FOO: bar
C-c * toggles it to
* #+FOO: bar
i.e. a headline.
Since in buffer settings are special lines, i.e. not a headline or part
of a plain list, I would expect an error so that any line starting with
#+ would not and could not be converted to a headline inadvertently. (In
my case I C-c *ed when I ought to have C-c C-ced.)
My set up is emacs 24.0.93.1 (i386-mingw-nt6.1.7601) of 2012-02-15 on
