title: vim not accepting abbreviation insertion before text
body: <p>i have this problem: i have this in my _vimrc:  </p>
  
  <blockquote>
    <p>iab dd \mathrm{d}</p>
  </blockquote>
  
  <p>and it works fine, <strong>except</strong> when I am editing a line and there is text on the right of the cursor (space or no space in between). Is there anything I can do to fix this? I couldn't find anything in the help files (or here!)..</p>
  
  <p>thanks!</p>
