[PATCH 10/16] man/curs_getch.3x: Fix content, style nits.

Content:

* More carefully distinguish escape sequences from the contents of a
  function key's string capabilitiy.  The latter is what the curses
  library actually processes, and attempts to disambiguate when
  a window's keypad mode is enabled.
* Add cross reference to terminfo(5) when mentioning string
  capabilities.

Style:
* De-italicize a term that has already been introduced.
