Hi Erik,
Since these[1] changes, language-native TAB can be achieved in code
blocks via C-c C-v C-x TAB and C-c C-v x TAB. We can add this to
org-tab-first-hook, controlled by a variable `org-src-tab-acts-natively'
as below. Carsten -- would you like to add this to Org, or leave it as a
user customisation?
