Log:
[MKHIVE]: Fix string byte size vs. count in number of characters confusion in append_multi_sz_value(); this was already OK in wine's code. Should fix corrupted multi-string entries in the livecd registry hives, for example...
In addition, always open the hive file to be created in write mode only.
