Expanding on what Corion said, you second while loop is what is causing the problem. Instead of 

    print $out $_ while s/^\s*\S+\s*//;

get rid of the inner while: 

    s/^\s*\S+\s*//;
    print $out;

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
