title: emacs space regex search
body: <p>I want to search for x spaces at the start of a line, using interactive regular search <code>^SPC&lt;</code> selects all lines starting with a variable number of spaces. According to emacs wiki</p>
  
  <pre><code> (setq search-whitespace-regexp " ")
  </code></pre>
  
  <p>Should solve this, but this reverses behavior: it selects one space when i'm entering multiple spaces in my search. I do not remember this behavior from earlier emacs (using 23.2 now). Is there a way to make interactive search select one space when entered one space and x spaces when entered x spaces?</p>
  
  <p>cheers
