title: bower automatically update bower.json
body: <p>I run the following commands using bower 1.0.0:</p>
  
  <pre><code>mkdir testdir;cd testdir
  bower init #accept defaults
  bower install jquery -s  #the -s is supposed to cause update of bower.json
  less bower.json
  </code></pre>
  
  <p>In bower.json I expect to see dependencies listed, but there are none.  What is going on?</p>
  
  <p>NOTE: <code>bower install jquery --save</code> does work</p>
  
  <p>NOTE:
  The option I am referring to was documented through <code>bower help install</code></p>
  
  <pre><code>**-S**, --save              Save installed packages into the project's bower.json dependencies
  </code></pre>
