 Summary of the bug:
 Editors like nano, Atom or other put automatically a line at the end of an
 text file.

 When drawtext now drawing a box behind the text the box is bigger then the
 text, because of this empty line in the text file at the end.

 It would be nice if the filter would ignore the very last empty line.
