  ## ws-butler -- an unobtrusive way to trim spaces from end of line

  - Only lines touched get trimmed.  If the white space at end of buffer is
    changed, then blank lines at the end of buffer are truncated respecting
    `require-final-newline`.

  - Trimming only happens when saving.

  ## What does unobtrusive mean?

  The user is not made explicitly aware when trimming happens.  You keep working
  and the butler takes care of whitespace for you.
