Can anyone tell me what is the effect of IRM ( smir / rmir ) on any other control sequences? For example, many ncurses programs seem to emit a DCH to produce a left-ward scrolling effect ( a great example is 'sl' ) I assumed that in replace mode, DCH would simply clobber the character(s) and leave everything else on the downstream line unaffected. However, when I allow that behavior to be the case, those programs generally don't seem to render correctly ( leaving artifacts behind ). Unfortunately, I cannot seem to find any canonical information on IRM as it relates to DCH ( or any other possibly affected control sequence ). From my experimentation, I assume that a DCH sequences always drags downstream characters left-ward but am ultimately unsure.
