pub fn undecorate(subject_line: &str) -> Undecorated<'_>Expand description
Take off a leading gitmoji that this hook wrote.
Only an emoji from COMMIT_TYPES counts, matched whole. An emoji the author
chose is theirs: it stays in the text and it counts against the subject
limit, because the limit is about what they wrote. split_leading_emoji
remains deliberately more permissive for parsing — this is about
measuring, and the two questions want different answers.
