title: coefplot: Putting names of regressions on y-axis
body: <p>The following code will generate a coefficient plot:</p>
  
  <pre><code>sysuse auto, clear
  regress price mpg trunk length turn if foreign==0
  estimates store D
  regress price mpg trunk length turn if foreign==1
  estimates store F
  coefplot D F, drop(_cons) xline(0)
  </code></pre>

  <p>However, I want to put custom names for each stored regression set of results on the <code>y-axis</code>:</p>

  <p>I tried various things about scale and label like <code>xrescale</code> but failed.</p>

  <p><strong>EDIT:</strong></p>
  
  <p>I do not mean to repeat <code>Domestic</code> and <code>Foreign</code>. I only want to keep <code>trunk</code>. 
  All other coefficients are not necessary. So <code>Domestic</code> and <code>Foreign</code> will appear just once.</p>
