Ep. 2 Setting up Git - Core Editor Configurations

[torwhite]

It's not obvious that changing the default editor only applies for commit messages without -m flag. It's mentioned later in episode 4 that commits without the -m flag will open the default text editor (and learners are directed back to ep. 2 to do changes). However, as this isn't elaborated on in ep. 2 learners have no context for what this default changes. Either move the default editor options from ep. 2 to ep. 4 (preferred - less jumping around in the lesson) or give a little more explanation in ep. 2 as to what that configuration changes (without overwhelming learners).
