Be smarter about recursively handling conditionals and variable/command expansions.  Don't recurse into conditional subdicts that won't be used because their associated condition is false.  Wait until conditions are evaluated and only recurse into subdicts that are being used immediately prior to merging them in. Review URL: http://codereview.chromium.org/51002
