[PATCH 14/14] man/curs_bkgd.3x: Fix style nits.

[G. Branden Robinson]

* Define `` and '' *roff strings for typographer's quotation marks.
* Use them instead of U+002D.
* Say "ncurses" instead of "this implementation".
* Set "ncurses" and "curses" in italics, not roman.
* Protect "ncurses" and function name literals from hyphenation.
* Break input lines after commas.
