Fwiw, native mostly just writes "SYNTAX ERROR", just
internationalized, so you can't really check it in a script. There are
some rare exceptions. The only one I remember is if you pass a
negative number as REG_DWORD data.

My consideration was that reg.exe would duplicate some of the
underlying function's logic and reg.exe would have to handle Reg*
return values anyway.
