* src/*: Fix overlapping strings highlighting each other.  new variables in edit_draw
          (slmatcharray, pbegin, paintok), new logic (with repeated setting od values in the
          array but its BFI after all).  FIXME: Need to create a new 'overlap'
        * src/*: Fix a silly issue with the argument to nregcomp, as it's confusing to the caller
        * src/nano.h: Change the color types to a compiler macro (COLORWIDTH), may not actually
          even be worth doing, but someday who knows how wide a color curses implementation might
          be, and maybe we'll even start checking for it in autoconf!
