Just tested `org-hlc-toggle-hidden-lines-cookies' with an org file:

,----------------------------------------------------
| 3 matches for "^\* " in buffer: org-outside-org.org
|      15:* Introduction [#30]
|      46:* Org-mode everywhere [#876]
|     923:* Screencasts  [#20]
`----------------------------------------------------

and

,-----------------------------------------------------------
| 12 matches for "^\*\*?\*? " in buffer: org-outside-org.org
|      15:* Introduction [#30]
|      46:* Org-mode everywhere

|     923:* Screencasts  [#20]
`-----------------------------------------------------------

and it seems to work here ... but thats because I always load
outshine.el and therefore took this function for granted:

,------------------------------------------------------------
| outline-body-visible-p is a Lisp function in `outshine.el'.
| 
| (outline-body-visible-p)
`------------------------------------------------------------

I fixed this in master right now, so if you pull the newest version it
should work. 

Note that org-hlc.el is 'wrong' in some ways:
- it only acts when called, not via a hook or so
- it actually modifies the buffer to insert and delete the cookies

but it works more or less, even for massive files.

I tried the right way (visibility change hook and overlays) and noticed
that my user experience went downhill pretty fast in big files - seems
that Emacs display engine is overwhelmed at some point. 

PS 
Why is flyspell-mode turned on automatically in the magit commit-msg
buffer now? I did not do anything about it and don't want it anyway ...
