Hi,

Thanks for you reply. I cannot understand the design of `org-src-preserve-indentation`.

Setting it to `nil` cause what described in my previous mail.

Setting it to `t` lose the leading two spaces indentation/alignment in the origin org buffer.

If it is `nil`, why inserting 2 leading spaces to the code in the org buffer except the line containing only spaces?

How can I get

#+BEGIN_SRC python

a = 1

b = 2

for i in range(10):

# 6 spaces before '#'

#+END_SRC

after exit `org-edit-special` ?

Best regards,

Jiajian Huang

This is not a bug. See `org-src-preserve-indentation'.
