My non-existent lisp skills were not able to determine what is causing it. (From *Messages* Buffer) Mark set unwind-protect: Symbol's value as variable is void: m Mark set Also I tried it on a larger region consisting of several lines and again it worked but in that case also removed the newlines. I don't really understand what the regex you used (\s-+) means. I understand `\s' to mean any single occurrence of any whitespace. And also understand the `+' operator to mean `at least one plus any number of matches to preceding regex. But again ... not sure what the `-' operator does. But I wondered if that `\s' could be changed to something a little more exclusive.... like maybe tabs and spaces only.. and if that would allow the function to work on more than one line?
