title: How to default/config git log -n param?
body: <p>I want to setup "git log" default params because it gives me too much information by default.</p>
  
  <p>Basically, I want to type "git log" but I want to see "git log -n 5"</p>
  
  <p>Do we have a way to do this? (without using alias, because I don't want to "git lg" instead of "git log")</p>
  
  <p>ps. I expect the answer will be something like "git config log.count 5"</p>
  
  <p>ps2. I managed to default the format with 
  git config format.pretty "format:%h-%an : %s"</p>
