[PATCH 11/52] man/tput.1: Correct some dates and OS references.

[G. Branden Robinson]

Content:
* Spell "4.3BSD-Reno" thus.
* Date it to 1990, not 1989.
  https://www.oreilly.com/openbook/opensources/book/kirkmck.html
* Date SVr4 to 1989.  (It was apparently _announced_ in 1988.)
  https://unix.org/what_is_unix/history_timeline.html

Style:
* Set "curses" in italics, not roman.

Markup:
* Prefer man(7) font style macros to *roff font selection escape
  sequences.
