Message:

Stop try to lex for matching braces in interpolation if the token_re matches an empty string. This fixes the infinite loop triggered by the test suite as a result of the change to Python 2.7 describe in ​http://bugs.python.org/issue16152 and reported in ​http://genshi.edgewall.org/ticket/540.
