More than one question:

        + what was the date for the "last 5.9 patch"?

        + what configure options did you use with "6.0"?
          (still pre-release, to check for regressions)

        + "6.0" can be configured to be the "same" as 5.9 using this option:
          Did you try building ncurses with that?

        + what I recall of readline is that it does not use much of ncurses'
          screen optimization.  But I haven't looked at it for quite a while.
          You _might_ have to recompile it to work with "6.0".
          Did you do that?

I'll have to investigate - simply have been short of time...
