Ahh yes, of course! Thank you, I have the save-excursion in the wrong
place, it should be
(when (save-excursion
(and nl-paras-fixed-p
(goto-char nl-markup-start)
(goto-char (muse-line-beginning-position))
(= (forward-line -1) 0)
(looking-at "^\\S-")))
(with-current-buffer nl-temp-buffer
(goto-char (point-min))
(insert "\n\n")))
I looked at it for ages without noticing that, thank you again.
Regards,
