AA notation starts becoming incorrectly encoded after passing azz

[slzero-X]

normally after azz it should become baa then bab then bac and so on, but however it seems that a small oversight in the encoder makes it fail to replace the second z that is in there even though it does so normally after zz is surpassed. I am currently studying it to fix this error. I'd be baffled if this error was never discovered by anyone using it.

Interesting - my own games has never gone that far up, so I never noticed. I don't currently have the time to look into it, but feel free to pull request if you find a fix.
