title: How make Vim fill Terminal window
body: <p>When running Vim in a Terminal, the vim window does not fill the entire screen space, which is very irritating when the terminal background color radically differs from vim's. Admittedly, one might want to keep them somewhat in sync, but given that I don't want that, how can I make vim stretch across the entire window?
  The screenshot below illustrates the problem.</p>
