Re: [dwm] make setlayout toggle

I have been using a bit different configuration here for some time and
am very happy with it. I don't toggle to the previous layout, but to
the floating layout. This way you avoid the confusion, and have an
easy way to go directly to any layout in no more than 2 clicks or key
strokes (in practice, setting the floating layout from tile is not the
same than setting it from monocle).
My implementation is a workaround to not modify dwm.c at all, but it
could be done much better in upstream dwm, because lt doesn't need to
be an array any more and we can get rid of sellt. I can write the
patch if there is some interest.
My 2 cts.

void
setltor1(const Arg *arg) {
        Arg a = {.v = &layouts[1]};

        setlayout((lt[sellt] == arg->v) ? &a : arg);
}

        { MODKEY, XK_space, setltor1, {.v =
&layouts[0]} },
        { MODKEY|ShiftMask, XK_space, setltor1, {.v = &layouts[2]} },

        { ClkLtSymbol, 0, Button1, setltor1,
         {.v = &layouts[0]} },
        { ClkLtSymbol, 0, Button2, setmfact,
  {.f = 1.65} },
        { ClkLtSymbol, 0, Button3, setltor1,
         {.v = &layouts[2]} },
        { ClkLtSymbol, 0, Button4, setmfact,
  {.f = +0.05} },
        { ClkLtSymbol, 0, Button5, setmfact,
  {.f = -0.05} },
