acorn loose throwing unexpected SyntaxError: Escape sequence in keyword function

[abose]

Hi,

I am integrating the latest tern and acorn into brackets code editor. But a few of our integration tests for acorn loose error tolerant parser is failing as it is throwing errors. I have added the minimal test that fails below:

acorn_loose.parse('function unicodeTabAfter\\u0009() {}');

Caught Critical error from: http://localhost:8000/src/thirdparty/acorn/dist/acorn_loose.js:248 message: Uncaught SyntaxError: Escape sequence in keyword function (1:9) 11 SyntaxError: Escape sequence in keyword function (1:9) (at acorn.js:2927:15)
