Kranu:
I had the same problem - did it about three times a while back and each time it reverted and that line was missing.
About a week ago, I tried again after someone posted about justification in another thread.
I don't recall what I did but I believe that I rebooted and did not open anything on the kindle, edited that file and rebooted again. I think one has to be careful that the kindle does not re-write that file if the kindle is in some "active" state where it writes back its cached (or similar stored file) version.
