I don't see anything like this.

The formatter doesn't call `fill-paragraph' at all. No wonder both do
not work in a way you would expect. 

The newline characters introduced in the output of the formatter were
present already in the original text. However, some objects ignore white
spaces on purpose. For example, [[foo bar]] and [[foo bar]] and [[foo\n
bar]] are equivalent, so the parser does not retain the distinction
between them. Hence links are always formatted on a single line.

Now, I'm not sure the formatter should call `fill-paragraph', for some
reasons:

- the original document could be using `visual-line-mode' so there's
  could be nothing to fill without Org knowing about it;

- Calling `fill-paragraph' requires full fontification, so `org-mode'
  would be initialised at every paragraph to fill;

- `fill-paragraph' depends heavily on user's configuration (custom link
  types, `org-fontify-emphasized-text', `org-hide-emphasis-markers',
  `org-pretty-entities'...) whereas the formatter is expected to be more
  neutral.

We could however, un-fill everything. But the output would be very
different. So, TRTD is not obvious.

This is related to the explanation above. Macros did the opposite of
links. The parser didn't remove meaningless spaces upon parsing macros.
So those would be inserted twice. I fixed this. Now macros show the same
behaviour as links: even multi-lines macros are inserted as a single
line.
