Make Window.alert/confirm/prompt default values the empty string
http://whatwg.org/html#the-window-object
Ad-hoc testing in Firefox Nightly and Opera 12.16 (Presto) reveal that
these browsers already treat missing arguments as the empty string.
Since this is not Web-exposed behavior, the risk is low.
The test case description no longer made sense, so rather than writing
new instructions for manual testing, just let -expected.txt say it.
