moz.txt

User Agent: Opera/9.80 (Windows NT 6.1; U; en) Presto/2.9.168 Version/11.52

Steps to reproduce:

I enter an ascii .txt file on the attached test page.




Actual results:

file should be sliced and shown as 64 character long sequences by javascript slice and filereader functions.


Expected results:

these slices should be prefixed by number (var counter) and postfixed  by ------@------

You can test the webkit function commented with chrome, also try commenting out line 
document.write('<pre>' + counter + '</pre>'); <!-- this bugs hard --> and it will show that the JIT is still broken.
