title: How to 'git commit' a single file/directory
body: <p>I tried the following command:</p>
  <pre><code>git commit path/to/my/file.ext -m 'my notes'
  </code></pre>
  <p>And received an error in Git version 1.5.2.1:</p>
  <pre><code>error: pathspec '-m' did not match any file(s) known to git.
  error: pathspec 'MY MESSAGE' did not match any file(s) known to git.
  </code></pre>
  <p>Is that incorrect syntax for a single file or directory commits?</p>
