org-fill-paragraph
org-fill-paragraph is an interactive compiled Lisp function in `org.el
'.
(org-fill-paragraph &optional JUSTIFY)
Fill element at point, when applicable.
This function only applies to comment blocks, comments, example
blocks and paragraphs. Also, as a special case, re-align table
when point is at one.
If JUSTIFY is non-nil (interactively, with prefix argument),
justify as well. If `sentence-end-double-space' is non-nil, then
period followed by one space does not end a sentence, so don't
break a line there. The variable `fill-column' controls the
width for filling.
For convenience, when point is at a plain list, an item or
a footnote definition, try to fill the first paragraph within.
