For simple rules like function spacing, we can auto-fix these across the code base so they are followed in a consistent way. To generate this patch, I ran: ./mach eslint devtools --no-ignore --fix After this, I reverted any changes to third party files that we really do want to ignore. MozReview-Commit-ID: 6Q8BApkAW20
