    git-arc: Accept message via -m when updating reviews.
    
    If a -m argument is given to update, it is passed through to arc diff
    when updating each review.  Note that if an empty message is specified
    via -m, arc diff will update the review without adding a note.
    
    If an -m argument is not given, then the user's editor is invoked by
    arc to supply a message for each review matching the previous
    behavior.
    
    This can be used to simplify the process for updating a set of
    reviews, e.g.:
    
      git checkout foo
      git rebase main
      git arc update -m "Rebase" main..
    
    This will rebase the 'foo' branch and update the reviews for all
    commits on the branch without invoking the user's editor separately
    for each review.
