Unified diff

The current manpage of script(1) says

"Certain interactive commands, such as vi(1), create garbage in the type-
script file.  The script utility works best with commands that do not ma-
nipulate the screen.  The results are meant to emulate a hardcopy termi-
nal, not an addressable one."

This patch fixes this issue by appropriately calling cfmakeraw.

Additional note: script(1) is currently able to record [-r] curses sessions
perfectly; only the playback functionality [-p] needs to be fixed. To reproduce
the problem, one may use the following program.

https://github.com/iiSeymour/game-of-life by GitHub user iiSeymour, which, in
the words of the author, is

"a python implementation of Conway's Game of Life using the curses module with
a small evolutionary twist."

This script was written for Linux; therefore, one must call "python gol.py" on
FreeBSD to bypass the #!
