Subject: patch 8.2.0281: two placed signs in the same line are not combined

Problem:    Two placed signs in the same line are not combined.  E.g. in the
            terminal debugger a breakpoint and the PC cannot be both be
            displayed.
Solution:   Combine the sign column and line highlight attributes.
