Then we'll see "sha1 for historical reasons"... bleh! Why do you think SHA-1 has anything to do with it? Git's sha1s could just as easily be 160 bits of a SHA-256 hash and there wouldn't be any user-visible difference. The term doesn't imply any particular significant connection to a particular algorithm. It could be like "pencil lead", which has never been made of lead, but is called that for no particularly important reason. -Daniel *This .sig left intentionally blank*
