Re: [O] Bug: babel results: output wrong location [7.8.09]

[Ista Zahn]

Hi Eric,

This is the second time I've reported a bug in org mode. Both times
the bug has been fixed the same day. I don't know of any other
software development project that even comes close to this. You guys
are simply amazing. Thank you so much for all your work on org-mode.

Best,
Ista
