+- ❗ Many string accessors that previously returned `Option<&str>` now return `Result<&str, Error>` (or `Result<Option<&str>, Error>`)
+  so callers can distinguish a missing value from a non-UTF-8 one.

+- ❗ `BlameHunk::final_signature`, `BlameHunk::final_committer`, `BlameHunk::orig_signature`, and `BlameHunk::orig_committer`
+  now return `Option` to avoid segfaults when signature information is missing.
