Issue #365 Bold/Italic nesting fix
The logic for the current regex for strong/em and em/strong was sound, but the way it was implemented caused some unintended side effects. Whether it is a quirk with regex in general or just with Python’s re engine, I am not sure. Put basically `(\*|_){3}` causes issues with nested bold/italic. So, allowing the group to be defined, and then using the group number to specify the remaining sequential chars is a better way that works more reliably `(\*|_)\2{2}. Test from issue #365 was also added to check for this case in the future.
