Thanks!

A couple of nits: maybe the comment that `org-back-to-heading' sets match
data should be deleted?  And there is a typo in the initial comment of
the test you added (thanks for adding it!): `:commends org' should be
`:comments org'.

Also, I found a couple of places in the code where `org-back-to-heading' is 
called
and then match data are used. I don't know if there is a problem or not, but it 
might
be worth double checking to make sure that the usage makes sense:

- org.el: l.20792 in `org-forward-heading-same-level'
- org-mouse.el: l.976 in `org-mouse-transform-to-outline'

I'll try to test these cases and report back but I can't promise when.
