evil-surround and vertical selection

[vimeitor]

Hello,

I think evil-surround doesn't work as expected with vertical selections. If you vertically select a few lines and press s, in vim whatever was selected will be deleted (surround will have no effect whatsoever); with evil-surround, it will surround whatever you had selected with the letter you pressed after s. I'm not sure that is expected behavior.

Merged @Tritlo's patch; this should be closed now. (this used to match vim-surround's behavior, but vim-surround has since changed)
