[PATCH] term(5): Fix excessively wide table.

[G. Branden Robinson]

The table formats to 84 columns on terminals.  Stop using page-local
`NS`/`NE` macros, which force an additional 4n of indentation that this
table cannot accommodate, in favor of portable man(7) macros, tbl(1)
usage, and one pair of `in` requests.

* On terminals, apply negative 2n indentation to fit the hex dump
  exhibit within 78 columns like the rest of the man page (on modern
  systems; older ones set man pages for a line length of 65n, upon which
  this exhibit has no hope, being 73n wide).  Retain 4n indentation on
  typesetters.

* Use table format specification to reduce type size by 1 point on
  typesetters (2 points was excessive) and use "CW" for the typeface.
  These are otherwise dubious things to attempt in man(7) source.  "CW"
  remains a non-portable font _name_; a forthcoming change will address
  that.
