Greasemonkey Script to rewrite gerrit download URL to a valid PowerShell command

RewriteGerritDownloadUrl.user.js

// This script will take the url you get from
// the Gerrit download field and replace
// the unix command/line separator ('&&') with
// a ';' which is accepted as line break in
// PowerShell
//
// This works with some Gerrit version previous 
// to 2.9 on Windows/Firefox. When we upgrades 
// to 2.9 I couldn't make the GreasMonkey script 
// work.
