Just updated the regexes to improve matching tagged lines.

This regex doesn't look broad enough. I'd suggest running it over the email addresses from the last couple hundred commits and makes sure it works. For example, it needs to contain ..

Currently, the email portion of the regex might be too broad. It currently doesn't enforce that @ is present, it just allows 1 or more non-whitespace characters to exist between the < >. Do you want me to enforce that what shows up there is some form of email?

I'm also broadening the name portion of the regex.
