There were some corner cases that were not handled (such as logging the
instance URL being processed). Additionally, code was simplified greatly
by centralizing the sanitization logic.
The goal is to separate initialization logic from command business
logic. Some initialization requires modifying the environment before we
instantiate many objects needed for implementing command behavior. If
those objects get instantiated, they will most likely already start
using files/directories/environment on the system and we can't modify
those while they're in use.
