I am more or less the one who asked for the current behavior because
I wanted to be able to easily comment blocks in SQL or ELisp or ...
--8<---------------cut here---------------start------------->8---
SELECT *
FROM table
WHERE <<cond1>> AND
-- <<cond2>> AND
<<cond3>>
--8<---------------cut here---------------end--------------->8---
However, as you say, in the SQL case, I could have used multiline
comments.
This is a pity it does not exist in ELisp.
However, your arguments 1 and 4 are important to me. Hence, I'd see no
objection to move in the direction you propose (insert whitespaces, so
that indentation is correctly done).
Best regards,
Seb
