title: equivalence of: git log --exclude-author?
body: <p>At work we have a git repo where the majority of all commits are automated commits by a bot user. There are times when I prefer to view a git log from that repo, but without seeing the auto commits. I guess it could be described as an inverted "git log --author" or a "git log --exclude-author=botuser", if such as option had existed.</p>
  
  <p>Currently I do the following, shortcuted to a bash alias.</p>
  
  <pre><code>git log --format="%H %aE" | grep -v -F botuser@domain | while read hash email; do git log -1 $hash; echo; done | less
  </code></pre>
  
  <p>My question is if there is a less hackish solution to what I want to accomplish?</p>
