Newline problem MSIE 8

[GoogleCodeExporter]

What steps will reproduce the problem?
1. parse a text like "a\n\nb"

What is the expected output? What do you see instead?
Only one newline is detected. It seems the two newlines are collapsed into one. 
The fault is inside String.split(..)

this.lines = text ? text.split(/\r?\n/) : [];

vs.

this.lines = text ? text.replace('\r','').split('\n') : [];

The latter works correctly. There's apparently a difference in using a regular 
expression or a ordinary string.

What version of the product are you using? On what operating system?
MSIE 8 mode (tested with MSIE9 and the compatibility options)

Please provide any additional information below.

Thank you for the bug report and workaround. i'll get it patched sometime this 
week but cannot test it on Windows (i don't own a copy).

Changed status to "started" so that i don't forget to merge this into the 
stable branch once it's proven okay.

Thanks for the test. i'll get this merged in to the "stable" branch as soon as 
i can test it out on Linux.

Hi! Should work fine on Linux as I initially patched it there :) Greets!

Hi! The question now is not so much whether it works on Linux (i am certain it 
will) but whether it breaks any of my wikis which themselves include wikiwym 
directly from Google Code (as opposed to having their own copy) ;). So far i 
haven't had the energy to confirm that. Until i get it merged into the "stable" 
branch, feel free to include the "trunk" copy into your project(s).
