The + character is not part of the 'basic regular expressions' in BSD grep. Use -E to enable extended (modern) regular expressions. Also remove escaping. This makes the commit msg hook work on macOS 14.2. Signed-off-by: Maarten Aertsen <maarten@nlnetlabs.nl> Signed-off-by: Robin Jarry <robin@jarry.cc>
