patch 8.1.1072: extending sign and foldcolumn below the text is confusing

Problem:    Extending sign and foldcolumn below the text is confusing.
Solution:   Let the sign and foldcolumn stop at the last text line, just like
            the line number column.  Also stop the command line window leader.
            (Christian Brabandt, closes #3964)
