Three small fixes.

1. `require_body` no longer counts trailers as a body

git commit -s -m "feat: x" adds a Signed-off-by: line, and that line alone passed CC011. A project that turns on both require_body and require_signed_off_by (FreeBSD atf does) got no body check at all. The trailer block at the end of the message is now left out before the body is judged. A trailer line here is a key with a hyphen (Signed-off-by, Co-authored-by, Change-Id) or one of Fixes, Closes, Resolves, Refs, Link, Cc, Bug; a body sentence such as Note: ... still counts as body.

$ printf 'feat: x\n\nSigned-off-by: T <[email protected]>\n' > m.txt
$ commit-check m.txt --require-body=true --compact
# before: exit 0
# after:
[FAIL] CC011 require-body: feat: x

2. `ignore_authors` as a string is split, not substring-matched

--ignore-authors and CCHK_IGNORE_AUTHORS take a comma-separated string, so people write the same in TOML. There it was tested with in on a string, a substring match: any author whose name was part of it skipped every check. It is now split on commas, like the flag; any other type exits 2. Same for [branch] ignore_authors.

$ cat c.toml
[commit]
ignore_authors = "renovate[bot], Test User 2"
$ git config user.name "Test User"
$ commit-check -c c.toml m.txt --compact   # m.txt is "bad"
# before:
⊘ skipped (not validated): message, subject-max-length, subject-min-length
# after:
[FAIL] CC001 message: bad
[FAIL] CC005 subject-min-length: bad

3. `-n` / `-e` read the author git will record

Before a commit exists, the author checks read user.name / user.email. Git records GIT_AUTHOR_NAME / GIT_AUTHOR_EMAIL first (set for the hooks by git commit --author), then author.name / author.email, then user.*. So --author slipped past author_email_pattern, and someone with author.email set to their work address failed on their personal user.email. The checks now follow git's order, as CC017 already does for the name.

$ git config user.email [email protected]
$ [email protected] commit-check -e --author-email-pattern='^t@corp\.com$' --compact
# before:
[FAIL] CC102 author-email: [email protected]
# after: exit 0

Also checked in a real commit-msg hook: git commit --author="A <[email protected]>" passes, a plain commit with [email protected] fails.

Tests

1625 passed, coverage 100% (lines and branches). The one local failure, test_load_config_file_permission_error, fails only when run as root and also fails on main.

Summary by CodeRabbit

Bug Fixes
- Commit author checks now follow Git’s author identity precedence, including configured identity fallbacks; explicitly selected commits continue to use their recorded identity.
- Commit messages containing only a subject and trailing trailers no longer count as having body text.
Configuration
- ignore_authors settings for commits and branches now accept comma-separated strings or lists of strings. Invalid value types produce a configuration error.

Walkthrough

The changes update how author identity is resolved, how commit body content is distinguished from trailers, and how ignore_authors settings are normalized and validated.

Changes: Author identity resolution

Layer / File(s)	Summary
Resolve prospective commit identity `commit_check/engine.py`, `tests/engine_test.py`	Non-revision checks now select author identity from `GIT_AUTHOR_`, then `author.`, then `user.*`, before falling back to the last commit. Tests cover environment and configuration precedence.

Commit body validation

Layer / File(s)	Summary
Exclude trailing trailers from body checks `commit_check/engine.py`, `tests/engine_test.py`	Body validation removes a final paragraph made up only of recognized trailer lines. Tests cover trailer-only messages and messages with body text.

Author-ignore configuration

Layer / File(s)	Summary
Normalize and validate author-ignore settings `commit_check/rule_builder.py`, `tests/rule_builder_test.py`	`ignore_authors` strings in the `commit` and `branch` sections are split and trimmed. Unsupported values raise `ConfigError`; tests check normalization and errors.

          fix: require a real body, split ignore_authors, read the recorded author

4495a6b

- require_body no longer counts a trailer block (git commit -s adds
  Signed-off-by) as a body.
- ignore_authors written as a string is split on commas, as the CLI
  flag and CCHK_IGNORE_AUTHORS are; it used to be a substring match,
  so an author named "Test User" skipped every check under
  "renovate[bot], Test User 2". Other types exit 2.
- -n / -e read GIT_AUTHOR_NAME / GIT_AUTHOR_EMAIL (set for the hooks
  by git commit --author), then author.name / author.email, then
  user.name / user.email: the identity git records.

          fix: match ignore_authors against author.name too

bbbcf7b

A piped message is checked against GIT_AUTHOR_NAME, then author.name, then
user.name. The ignore_authors lookup skipped author.name, so it could match
a different identity than the one the author checks read.
