Hi,

needed a check at several occassions, if the current line
contains printable characters.

What about the following to solve this?

(defun empty-line-p ()
  "Returns t if cursor is at an empty line "
  (interactive)
  (save-excursion
    (beginning-of-line)
  (if
      (looking-at "^[ \t\f\r]*$")
      t
    nil)))
