When using refill-mode in combination with org-mode adding a new section or a list item at the end of the buffer, obviously because refill-mode steps in and deletes the line break before the headline marker or the list marker.
Steps to reproduce: 1. Launch emacs -Q 2. Open a empty buffer and activate org-mode and refill-mode 3. Type `* This is a headline<M-RET>` Expected behavior: Buffer contents should be ``` * This is a headline * ``` Actual behavior: Buffer contens is ``` * this is a headline * ``` Obviously right after typing <M-RET> and thus inserting <line break>+"*" refill-mode steps in and interprets the second line as part of the paragraph. Remarks: * The problem does not occur when there is text after the place where the new headline is inserted * The problem occurs with any kinds of headlines as well as with list items. I tried to tweak paragraph-start, but I was not able to get the behavior I was expecting.
