Wrap command descriptions to 80 characters. Convert some string options
to symbols (where possible). Align options in code. Remove dots in the
end of switch descriptions.

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!).
