bug or a feature? If latter, how do I comment current line in org-babel?
If this commit is not merged into the maint branch, you would need to git clone the master branch and build org locally to get it. The version available via package.el is the latest build of only the maint branch.
My Org-mode version is 8.3.6 (8.3.6-7-g4d7d52-elpaplus @ /.../.emacs.d/elpa/org-plus-contrib-20161024/)
Looking at the commit date, it is 2016-10-15 10:31:25 (GMT)
Any way I can test it whether I have this commit or not?
