Re: org-babel-detangle not working

["Jaakko Järvi" <jarvij@gmail.com>]

Hi, 

I don’t think there’s much more to explain
or a more minimum example to create. The behavior is exactly 
as you specified, and it is not an expected or desired behavior.
I’m happy to try to clarify more, but I don’t at this point know
what is unclear about the problem.

Best, 

  Jaakko
