clojureRegexpEscape changes

guns · guns · commit 23fa4fb22cdb · 2013-03-22T16:53:55.000-05:00
* Remove \. since it expands to its literal self, unlike \t or \011

* Limit the \x{…} digits to the strlen of Character.MAX_CODE_POINT in
  hexadecimal. The compiler accepts any length of leading zeroes in the
  braces, but the docs only define from MIN_CODE_POINT to MAX_CODE_POINT
