cat-file: split batch "buf" into two variables
We use the "buf" strbuf for two things: to read incoming lines, and as a scratch space for test-expanding the user-provided format. Let's split this into two variables with descriptive names, which makes their purpose and lifetime more clear. It will also help in a future patch when we start using the "output" buffer for more expansions. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
