title: blank.lines.skip = TRUE fails with read.fwf?
body: <p>There are four blank lines at the end of my file.</p>
  
  <pre><code>&gt; data=read.fwf("test2",head=F,widths=c(3,1,-3,4,-1,4),blank.lines.skip = TRUE)  
  &gt; data  
  </code></pre>
  
  <p>When I run this code, the blank.lines.skip argument is ignored. I still get blank lines in my output.</p>
  
  <p>The file is:</p>
  
  <pre><code>x1     F          1890 1962  
  x2                1857 1936  
  x3                1900 1978  
  x4                1902 1994  
  x5        F       1878 1939 
  </code></pre>
  
  <p>and four blank lines at the end. </p>
