Function extract_coauthors
pub fn extract_coauthors(message: &str) -> Vec<String>Expand description
Extract Co-Authored-By: trailer values from a commit message.
Returns the email (lowercased) when the Name <email> form is present,
or the whole body (lowercased, trimmed) as a fallback for non-standard
trailers. The email form is preferred because it is more identity-stable
than display names.
Matching is case-insensitive on the trailer key; the returned strings are always lowercased so callers can do case-insensitive dedup.
