/*** NOTE ***
 * Due to the way, iText inserts a CR/LF at the end of the outermonst unordered list, the [CR] command is handled
 * specially by PdfBulletListPlainEnd.java when it occurs immediately after the end of a bullet list. If changes
 * are made to this class above, consider whether they apply to that code as well.
