It is in agreement with my expectation that the fix should not be 
LaTeX-specific. That is why I raised the issue in this thread.

What I do not like with this regexp is that it matches every newline 
character, not only blank lines:

(replace-regexp-in-string
 (rx (1+ (0+ space) "\n")) "[n]"
 "a   \nb")
"a[n]b"

If you still believe that a fix should be for LaTeX only then I would 
consider extra "\n": (rx "\n" (1+ (0+ space) "\n"))

I have realized that the following is a kind of pitfall in Org syntax:

#+macro: comment
Another
{{{comment(Paragraph separator! Do you expect it?)}}}
paragraph.
