  # If the previous command returns a non-zero exit code, that means gulp has
  # modified some files in version control. This shouldn't happen, developers
  # should remember to run gulp before committing. (We're excluding
  # package-lock.json, as changes can be caused merely by a different version
  # of npm.)
