Unless git uses regex, it is almost impossible to verify that the regex is same as their validation. What if git's validation changes. Even looking at the corrected regex I am not sure what would happen for strings like '<a@a.com>>' or '<' or 'x <a>'. Not saying the github's corrected regex is wrong, but it is a mental challenge to verify it.
