title: ask committer name and email every git commit
body: <p>if you git commit without telling git who you are you get a message like this</p>
  <pre><code>$ git commit -m &quot;From Qworp&quot;
  
  *** Please tell me who you are.
  
  Run
  
    git config --global user.email &quot;you@example.com&quot;
    git config --global user.name &quot;Your Name&quot;
  
  to set your account's default identity.
  Omit --global to set the identity only in this repository.
  </code></pre>
  <p>How can I make <em>every single</em>  <code>git commit</code> prompt for user.name and user.email? something like</p>
  <pre><code>$ git commit -am &quot;From Qworp&quot;
  user.name: Qworp
  user.email: qworp@qworp.com
  [master be42c9e] From Qworp
   1 file changed, 5 insertions(+), 5 deletions(-)
  ...
  $ git commit -am &quot;Now Ace&quot;
  user.name: Ace
  user.email: ace@qworp.com
  [master 56ec176] Now Ace
   1 file changed, 2 insertions(+), 1 deletions(-)
  </code></pre>
  <p>And set author and committer details based on that?</p>
