title: How to remove extra blank above command status-line in vim?
body: <p>I managed to get an extra blank link in the bottom-of-the-screen status area in my vim, i.e. in insert mode there is a blank link between the last line of the buffer I'm editing and the command status line where it says "INSERT"", i.e. an <em>extra</em> line above the status line. (See screenshot below for illustration.)</p>
  
  <p>It happened like this. I installed the vim-airline plugin. Then, in MacVim, I accidentally dragging the bottom area up by a few lines. I tried to put it back but I could only get it down to 2 lines. I've even uninstalled vim-airline to no avail.</p>
  
  <p>The extra line is there whether in MacVim or vim (via terminal on my OS X system, obviously).</p>
  
  <p>How do I get rid of that extra line and reset the status bar area back to default? </p>
