Copy-pasting don't get hard-lines

[DamienCassou]

When copy-pasting paragraphs, you won't get any hard newlines. This means all paragraphs will be merged. Even though not strictly the responsibility of this package, I would suggest adding a command that adds hard linebreaks at the end of paragraphs.

I, too, stumbled on this problem. For now, I've bound M-S-q to the following function, to easily fix such paragraphs 'manually':

(defun use-hard-newlines-guess (&optional beg end &rest _ignore)
  "Intuit hard newlines: mark as hard any newlines in region
  that precede a paragraph-start line."
  (interactive "r")
  (save-restriction
    (when (and beg end)
      (narrow-to-region beg end))
    ;; re-enable the use-hard-newlines minor mode, requesting to guess
    ;; which newlines should be marked as hard
    (use-hard-newlines -1 'guess)
    (use-hard-newlines 1 'guess)
    (messages-are-flowing--mark-hard-newlines (point-min) (point-max))))

The &rest _ignore is to support being added to the 'after-change-functions hook.
