  - pre-upload: show all possible fixup commands while running
    
    This allows people to quickly run fixup commands themselves if they
    want.  This is helpful as we only offer to run the command if there
    is one fixup in the latest commit.
    
    Show these as a summary at the end so hopefully it's a little easier
    for users to access if they want to copy & paste the command.
