I've noticed a few transactions that have zero-length input and/or =
output scripts. There's a couple examples in block =
0000000000000159a27442ee8b7f9ffad0cd799b003eafe007de9fbb47bd6ce7:

af32bb06f12f2ae5fdb7face7cd272be67c923e86b7a66a76ded02d954c2f94d
Is there ever a legitimate reason to create a transaction with a =
zero-length script? Should the protocol even allow it?
