yes i do re-purpose the right alt key, and left&right windows keys.

hmmm. i hit the escape key then the "w" key for M-w.

ok. done below. it feels to me like the issue is the len/newlen is maybe
one char to many. i'm thinking this because emacs correctly picks up my M-w,
but then ALSO inserts "w" into the buffer.

i don't know if this helps or not, but the following code also works
for me:

 default:
   if (len == 0
     && (keysym & 0xfff0) != 0xff70
     && (keysym & 0xfff0) != 0xffe0)
   /* generate a keycode for every remaining keypress */
   sprintf ((char *)kbuf, "\033[%x;%xA", (unsigned char)ev.state, (unsigned short)keysym);
   newlen = 0; // THIS FIXES IT FOR ME
   break;

original 4.7:

(%:~/src/lm-4.0)- od -a 
^[w
0000000 esc   w  nl
0000003

patched 4.7:
(%:/opt/src/rxvt-unicode-4.7)- od -a
^[w
0000000 esc   w  nl
0000003

darn they are the same.
