Summary: [>> $big1 $big2] incorrectly returns 0 

Initial Comment:

For example:

% >> -0x8000000000000001 0x8000000000000000
0

Result should be -1.  [>> $big $wide] is ok:

% >> -0x8000000000000001 0x7fffffffffffffff
-1

And clearly, shifting that -1 one more bit
ought to return -1 again, not 0.

Perhaps a clue... it's not always broken:

% >> -0x8000000000000000 0x8000000000000000
-1
