(See documentation on mode-line-format, also see the default value of mode-line-format and all the parts it gets built from.) Instead of using a list with a negative number at the front, you might prefer defining a function to ellipsize a string. You then get to choose an ellipsis character and whether to truncate from the start, end or middle.
