* fix: Remove spurious blank lines Remove extraneous blank lines introduced by deletion of 'use strict'; pragmas. Also fix the location of the goog.declareModuleId call in core/utils/array.ts. * fix: Add missing double-blank-line before body of modules Our convention is to have two blank lines between the imports (or module ID, if there are no imports) and the beginning of the body of the module. Enforce this. * fix: one addition format error for PR #6243
