[PATCH v2 0/2] t: add and use a commit_body test helper

Junio pointed out that t7509-commit-authorship.sh defines its own local message_body() helper that wraps the same "git cat-file commit | sed" idiom commit_body was introduced to replace, which the first version of this series missed. Rechecking the whole idiom by its sed address, rather than by grepping for "cat-file", turned up one more inline occurrence with a spacing/escaping variant in t3404-rebase-interactive.sh that also didn't match the four spellings enumerated in v1.

Changes since v1:

  2/2: fold in t7509's message_body helper (drop it, convert its six
       call sites to commit_body) and the missed inline site in t3404.
       Site count is now 61 in 12 files, plus the removed helper.

  test-lib-functions: add commit_body helper
  t: use commit_body to extract commit message bodies
