SRC block with `-i' switch seems to solve the problem (was: comment alignment not lining up / C++//l OrgSrc Abbrev / Releasing Emacs 26.1)

[Van L <van@scratch.space>]

Hello Eli.

Thanks for solving the problem with chinese input method’s link reference which was broken due to an 18yo typo.

Separately, the following is a different bug.

I reported this bug which didn’t get acknowledged as far as I can tell.

I think the bug isn’t a bug now.

It isn’t a bug if instead of using EXAMPLE block I use SRC block with the `-i’ switch and the indenting will be preserved properly.

Perhaps the Org Mode documentation about the `-i’ switch for SRC block can demonstrate an example, for Python especially, to get the point across about preserving indentation and reduce the chance of misunderstanding or missing the point.
