Bug: org-fill-paragraph deletes an extra line [9.1.11 (9.1.11-2-ge3b1c6-elpa @ /home/yminsky/.emacs.d/elpa/org-9.1.11/)]

[Yaron Minsky <yminsky@gmail.com>]

This problem crops up when I install 9.1.11. I was previously using an
8.* version of org, and didn't see an issue. The basic problem is that
every time I do M-q to fill a paragraph, it deletes an extra line from
right after the paragraph, eventually sucking in following headers and
paragraphs into the present paragraph.

Oddly, it also gets indentation wrong. So if I start with this:

- asdf asdfasdf asdfasdf asdfasdf asdfasdf asdfasdf asdfasdf asdfasdf
  asdfasdf asdfasdf asdfasdf asdfasdf asdfasdf asdfasdf asdfasdf
  asdfasdf asdfasdf asdfasdf asdfasdf asdfasdf asdfasdf asdfasdf
  asdfasdf asdfasdf asdf

And I try to fill the paragraph, I'll get this:

- asdf asdfasdf asdfasdf asdfasdf asdfasdf asdfasdf asdfasdf asdfasdf
asdfasdf asdfasdf asdfasdf asdfasdf asdfasdf asdfasdf asdfasdf
asdfasdf asdfasdf asdfasdf asdfasdf asdfasdf asdfasdf asdfasdf
asdfasdf asdfasdf asdf

I wasn't able to find a description of this error by googling around, sadly.
