Hello,

Thanks for you reply.

I'm not trying to get the empty line. The example snippet is just for
illustration.

First of all, I really like the two space indentation/alignment when
`org-src-preserve-indentation`
is set to `nil`. And since org does not indent the empty line*s, *the fields
one empty of `yasnippet` or packages which generate empty lines can not
work properly and the indentation of these line*s* are violated
as mentioned in the second mail.

Best regards,
Jiajian Huang
