Copied from issue 6135 in Chromium (http://crbug.com/6135).

Add OK or FAIL after other browsers where you have tested this issue:
Safari 3: OK
Firefox 3: OK
IE 7: OK
Chromium: FAIL

What steps will reproduce the problem?
1. Make Chromium render a complex text (e.g. a Hebrew text containing nikkuds)
whose "white-space" property is "nowrap" or "normal"

What is the expected result?
Chromium should treat a line-break characters (U+000A and U+000D) in the text
as whitespace.

What happens instead?
Chromium treats line-break characters in the text as zero-width spaces.

Please provide any additional information below. Attach a screenshot if
possible.
This issue is caused by its UniscribeHelper::adjustSpaceAdvances() function
that mis-treats the line-break characters as zero-width spaces.
