Evil numbered register behavior vis-a-vis vim

[Allen Li]

Hi,

I believe you are running into this bug:
https://bitbucket.org/lyro/evil/issue/339/zero-register-0-has-odd-behavior

Basically, registers 0-9 are mapped to the emacs kill ring.  I don't
have any experience to say how this would be fixed though.
