Using a similar example, another indentation bug has been revealed:
1. emacs -Q
2. Create an Org file with the following contents:
- 1
- 2
- 3
- 4
- 5
#+begin_src yaml
a:
b:
c:
d:
#+end_src
Everything indented using spaces, including "d:" that uses 8 spaces,
which should remain spaces since yaml-mode uses spaces for indentation.
3. M-x whitespace-mode
4. Move point to item 5 and press M-<right> 3 times
5. Observe "d:" indented using two tabs with all the spaces replaced by tabs.
The cause is the following line in `org-list-struct-apply-struct'
[[file:~/Git/org-mode/lisp/org-list.el::indent-line-to (+
(org-current-text-indentation) delta)))]]
It calls `indent-line-to' that replaces spaces with tabs according to
current value of indent-tabs-mode in Org buffer.
