[PATCH 052/177] man/curs_inopts.3x: Fix content and style nits.

[G. Branden Robinson]

Content:
* It's not the library (ncurses or tinfo) itself that needs to be
  "initialized" before use of these functions, but the `TERMINAL` data
  structure corresponding to a device the library manages.

Style:
* Use better preposition.
* Use less awkward phrasing.
