[PATCH 19/34] man/ncurses.3x: Revise `U8` capability example.

[G. Branden Robinson]

* Use `EX`/`EE` macros instead of formatter requests.
* Use `\-` special character escape sequence to get "ASCII" hyphen-minus
  characters in example, to facilitate copy-and-paste from PDF or UTF-8
  terminals.

(Normally, one does not use `\-` for a hyphen in *roff document
composition, but this is an example of ISO 646/ASCII/Unicode Basic Latin
input.)
