Problem indenting plain lists

[Anthony Lander <anthonylander@yahoo.com>]

I'm on Org-mode version 6.33 (release_6.33) and I'm having a problem  
with indenting. Given this little org file:

* Heading 1
   - notes 1
   - notes 2
     - more notes
*** Heading 2
     - even more notes
     - even more notes

I want to make a new plain list item before "notes 1".

If I put my cursor at the start of the line that says "- notes 1",  
then RET and C-p (ie make a blank line) and then type -TAB nothing  
happens. If I type - and then use either demote heading or demote  
subtree, it indents the current line, but also demotes all the lines  
below it. Is there a way to just indent the hyphen so it lines up with  
other notes lines?

Thanks,
