(Related to #116 which only adressed REG_BINARY values.)
If you create an empty value of one of the following types and try to read the values using Advapi32Util.registryGetValues() you will get an exception:
REG_SZ
REG_EXPAND_SZ
REG_MULTI_SZ
REG_NONE
The Exception:
java.lang.IllegalArgumentException: Allocation size must be greater than zero

I have written unit test and code to solve the problem in a stubbed environment (I haven't had the time to get the full build environment for jna up and running yet), I will provide a pull request with the fix as soon as I've applied the changes from my stubbed environment to my real jna repo clone.
Question: should unit tests and the fix be checked in as two separate commits or as one commit?
