patch 8.2.0324: text property not updated correctly when inserting/deleting

Problem:    Text property not updated correctly when inserting/deleting.
Solution:   Use the right column when deleting. Make zero-width text
            properties respect start_incl and end_incl. (Axel Forsman,
            closes #5696, closes #5679)
