Re: [RFC] get_sha1() shorthands for blob/tree objects

Not that my voice carries much weight, but a coworker has been
asking for this feature to be added to pg for months.  I've just
been too lazy to get around to writing the shell code to do it.
Making it part of git cat-file seems like a good idea, making it
usable by other tools like git diff just rocks.  :-)

I think its a very worthwhile addition.
