title: git command could not be found and could not find ssh-agent
body: <p>I was on GitHub today and realized I was behind on updates from a repo. I tried to <em>fetch</em> updates, but it failed from the outset. I received two messages when I started up Git Shell (from GitHub for Windows):</p>
  <blockquote>
  <p>Warning: git command could not be found. Please create an alias or add it to your PATH.</p>
  <p>Warning: Could not find ssh-agent.</p>
  </blockquote>
  <p>When I attempted to enter &quot;$ git fetch origin&quot;, I got the following error message:</p>
  <blockquote>
  <p>The term '$' is not recognized as the name of a cmdlet, function, script file,
  or operable program. Check the spelling of the name, or if a path was included,
  verify that the path is correct and try again.</p>
  </blockquote>
  <p>I also tried omitting the $ sign, but that didn't change anything.</p>
  <p>I have no clue what's going on, the last time I used the Shell (beginning of this month), it did not do this. I have tried adding the path to git.exe to the PATH environment variable, but that did not work - nothing appeared to change. I have not restarted my computer after doing so, is that the problem? I have also never set up Git to use SSH.</p>
