Re: [PATCH 2/2] read-tree: at least one tree-ish argument is required

Quoting Junio C Hamano [off-list ref]

Come back with a proof that there has never existed any script that uses
"read-tree" without arguments to purge the index, and I'd immediately
accept and apply the patch to retroactively forbid what the implementation
has allowed users to do for a long time.

For what it's worth, I compiled the very first version of git

 commit e83c5163316f89bfbde7d9ab23ca2e25604af290
 Author: Linus Torvalds [off-list ref]
 Date:   Thu Apr 7 15:13:13 2005 -0700

     Initial revision of "git", the information manager from hell

and its read-tree fails with 

  read-tree: read-tree <key>

Is it a proof enough?
