title: git: Commit multiple files but add messages
body: <p>I have tons of files in my repo, and sometimes I work on 20 files and I want to commit all of them.  But, I would like to add a message for each.</p>
  
  <p>How can I add all of these files that have been updated and also add a message for each without having do run a command for each one manually?  Is this possible to do a bulk run and have it prompt me to add a message for each one?</p>
