title: How do you automatically remove the preview window after autocompletion in Vim?
body: <p>I'm using <code>omnifunc=pythoncomplete</code>. When autocompleting a word (e.g., <code>os.&lt;something&gt;</code>), I get the list of eligible class members and functions, as expected, as well as a scratch buffer preview window with documentation about the selected member or function. This is great, but after selecting the function I want, the preview window remains. </p>
  
  <p>I can get rid of it with  <code>:pc</code>, but I'd like it just to automatically disappear after I've selected my function, a la Eclipse. I've played around with <code>completeopt</code> but to no avail.</p>
