Besides a couple of bugfixes in patches 0008 & 0009, I have also 
uploaded a patch (0010) that mitigates most of the performance drop in 
NT format when using --encoding=<cp> (where <cp> is a codepage like 
cp1252, not UTF-8).

The previous code was "strlen(key), convert whole key, put into buffer" 
in three separate steps. The new code is just "put into buffer, 
converting on the fly" like we do with UTF-8. My speed went from some 
15500K to over 26000K (while default "raw" mode is around 27000K)

Now, running --enc=<cp> is a bit faster than --enc=utf8, which is 
expected as UTF-8 is more complex.
