Conditionally enable double key logic according to:
private browsing mode or privacy.thirdparty.isolate preference and

michael@0	2	* Check that builtin character classes within ranges produce syntax

michael@0	5	* Note that, per the extension in bug 351463, SpiderMonkey permits hyphens
michael@0	6	* adjacent to character class escapes in character classes, treating them as a
michael@0	7	* hyphen pattern character. Therefore /[\d-\s]/ is okay

michael@0	9	* Note: /\b/ is the backspace escape, which is a single pattern character,
michael@0	10	* though it looks deceptively like a character class.
