removed the word "Second" form the beginning of the 2nd list item and labelled it as 2

on Repetitions section. Also did alignment.

 Textual scope is based on the order that things appear in source files, or even
 across multiple files, and is the default scoping. It is explained further below.
 Path-based scope works exactly the same way that item scoping does. The scoping,
