[PATCH 2/2] commit.c: rename find_commit_header to find_header

["John Cai via GitGitGadget" <gitgitgadget@gmail.com>]

From: John Cai <johncai86@gmail.com>

Since find_commit_header's logic is not just limited to commit objects,
we can rename this to a more general find_header function so it's
clearer that it can be used in a more general way.
