Summary of the new feature or changed behavior

A new (off-by-default) rule has been added to PSScriptAnalyzer called AvoidSemiColonsAsLineTerminators. When enabled, it warns if a semi-colon is the last token on a line.

For example:

Wrong

Install-Module -Name PSScriptAnalyzer; $a = 1 + $b;

Install-Module -Name PSScriptAnalyzer;
$a = 1 + $b

Correct

Install-Module -Name PSScriptAnalyzer; $a = 1 + $b

Install-Module -Name PSScriptAnalyzer
$a = 1 + $b
