Hmm...  If I use nano -N on a DOS file, then I see at the end
of each and every line a ^M.  Don't you see this?

Maybe the explanation of the option should be improved: it
doesn't convert the actual file, it just converts the internal

I think that in general when one edits a file, one surely does
not want the editor to change the format of the file without
having explicitly asked it to do that.  Secondly I think it is
not an editor's task to convert formats -- sure, it would be
cool if it could do that, but it is an extra bell or whistle.  There
are tools like dos2unix or simple seds that can do that.
