Hi I personally don't see a particular need for this, it's something that can be tidied up as people make other changes in the area. Certainly you are trying to touch a lot of different places at once here which is usually not the best approach even for something minor. You'd probably be better sending separate diffs to the right people, at least where that is easy to figure out.
But in any case, the libedit bits should go upstream to NetBSD and libcurses/libform/libpanel bits upstream to Thomas Dickey. Hmm libedit needs an update...
