Fatal error(s) on direct script access.

[thefrosty]

Calling a WordPress function like esc_html_e in a conditional check for ! function_exists( 'add_action' ) as seen here: https://github.com/boogah/force-strong-passwords/blob/master/slt-force-strong-passwords.php#L25 usually means someone is trying to directly hit the file in which case esc_html_e doesn't exist and will throw a fatal error.
