title: Vim path separator & auto-completion
body: <p>Working on web stuff, in windows, to be hosted on linux.</p>
  
  <p>Completing paths with ^X^F automatically inserts "\" as the path separator on windows, which is quite correct, but not what I want, so:</p>
  
  <p>Is there a way I can tell it to use "/" as the path separator for auto-completion regardless of OS?</p>
