unfill-paragraph, unfill-region
Emacs does not have a “unfill-paragraph” command to do the inverse of “fill”. Here's the solution:

URL `http://xahlee.info/emacs/emacs/emacs_unfill-paragraph.html' Version 2016-07-13" (interactive) (let ((fill-column most-positive-fixnum)) (fill-paragraph)))
(defun xah-unfill-region (start end) "Replace newline chars in region by single spaces. This command does the inverse of `fill-region'. URL `http://xahlee.info/emacs/emacs/emacs_unfill-paragraph.html' Version 2016-07-13" (interactive "r") (let ((fill-column most-positive-fixnum)) (fill-region start end)))
