patch 9.1.0707: [security]: invalid cursor position may cause a crash
Problem: [security]: invalid cursor position may cause a crash
(after v9.1.0038)
Solution: Set cursor to the last character in a line, if it would
otherwise point to beyond the line; no tests added, as it
is unclear how to reproduce this.
