[me]: Integrate better with papersize.tmac.

* tmac/e.tmac: Integrate better with papersize.tmac by no longer forcing
  line (and title) length to 6 inches for typesetters on initialization.
  Gather default line length from output device description, possibly
  modified later (by other macro file or input).  No change to terminal
  ("nroff mode") output.

* NEWS: Add item.

Tested as follows.
