patch 8.2.4960: text properties that cross lines not updated for deleted line

Problem:    Text properties that cross line boundary are not correctly updated
            for a deleted line.
Solution:   Correct computing location of text property entry. (Paul Ollis,
            closes #10431, closes #10430)
