[issue7877] Iterators over _winreg EnumKey and EnumValue results

Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
WindowsError: [Error 6] The handle is invalid

I suspect that .iterkeys / .itervalues would be more
acceptable spellings as those mirror the dict methods.
Whether the idea of extending _winreg beyond the absolute
basics will fly I'm not sure. I don't often use it, but
this would be useful if I did...
