title: ctags regex for multiple declarations in one line
body: <p>I'm writing a .ctags file for a custom language... Like most languages, it allows for multiple variable declarations in one line.. i.e.:</p>
  
  <pre><code>int a, b, c;
  </code></pre>
  
  <p>I have a basic regex which recognizes 'a':</p>
  
  <pre><code>--regex-mylang=/^[ \t]*int[ \t]*([a-zA-Z_0-9]+)/\1/v,variable/
  </code></pre>
  
  <p>How do I modify this to have it match 'b' and 'c', as well? I can't find anything in ctags documentation that deals with multiple matches in a single line.</p>
