John "banister" Mair describes the following key features of commands
as classes:
1. It enables people to extend them by either subclassing or
monkeypatching.
2. It enables them to provide their own API, so that for example, the
Pry::Command::Edit class could have class methods for people to
configure it.
Please, note that I didn't touch easter eggs commands. I also prettified
some strings (your source code reading experience should vastly improve!).
