[PATCH 074/100] man/ncurses.3x: Revise "Padding Differences" subsection.

[G. Branden Robinson]

Content:
* Refer to terminfo capabilities by name _and_ code; including the
  former is far less cryptic.

Style:
* Tighten wording.
* Set "curses" in italics.
* Favor active voice over passive.
* Prefer term "terminal" to "tty".
* Say "ncurses" instead of "this implementation".

Markup:
* Break input lines after commas and around multi-word parentheticals.
* Favor man(7) font style macros over *roff font selection escape
  sequences, except for man page cross references (because
  man/make_sed.sh recognizes only certain patterns when rewriting such
  cross references).
