Hi Séb,

Yes. If people think it is worthwhile, we could make it so that these
are controlled by variables `org-src-comment-natively' and
`org-src-indent-natively'. However, currently that is not the case. The
only such variable currently is `org-src-tab-acts-natively'.

By the way, please note that there is a minor wrinkle: if you place
point in the #+end_src line in the Org buffer, then it goes to the
beginning of the last line of code in the edit buffer, and the region
will not contain what you were intending (all the code). I'm going to
submit a patch so that point goes to the end of the code in this case.
