Aadhavan Srinivasan 25cb79f01b Changed the value of EPSILON, so that we can use the NUL character ... (which it used to be) in a regex; Also added code to detect escaped backslashes Specifically, I replace an escaped backslash with a metacharacter, then replace it back later on. This prevents problems, like detecting whether the opening bracket is escaped in '\\[a]'.		9 hours ago
