My first version of this message did not seem to make it to the
net, so here we go agin.
I posted a patch to kernel/console.c a few weeks back that was
to enable linewrap. Later after I noticed how it broke the full
screen editors I indicated one should not use the patch.
I have a new version that checks the mode of the tty before
enabling linewrap. This gets around the problem of one needing
to turn off linewrap when in vi.
In kernel/console.c put:
if (v->ccol >(LINEWRAPPOS-2)) {
     i = (v==&vduinfo[1]); /* console 0 or 1 */
      if ((tty_struct[i].tty_mode & (RAW | CBREAK)) ==0) {
         if (v->crow ==NROW-1) {
            for (i=0; i<NROW-1; i++)
              vducpyline(i+1,i);
            vduclrline(i);
            vdumoveto(v->crow,0);
         } else vdumoveto(v->crow +1,0);
      } else vdumoveto(v->crow, v->ccol+1);
} else vdumoveto(v->crow, v->ccol+1);

I think the original code had just vdumoveto(v->crow,v->ccol+1);
You will need to #define LINEWRAPPOS 80 at the top of the file.
You may also need a 'int i;' at the top of the function, vduput
which is where the changes are.

There is a bug in that when you are at the top of the screen
in elvis and hit 9 uparrow the screen does not get updated
correctly. It only updates correctly if you go up one line
at a time. Anyone have a fix to that one?
