style.lua(9): Clarify local variable guideline

Browse Source 
The intent of this guideline is to avoid creating global variables in module
scope. Its main purpose is to serve as a reminder that variables at module
scope also need to be declared.

We want to avoid global variables in general, but this is easier to mess up
when designing things in the module scope.
