Fixes in 1991/westley + alt code

The alt code is based on the author's remarks where the computer will
always win (supposedly :-) :-) ). It involves the new script ttt.alt.sh
which is copied to ttt.alt with make. This script has changes from
ttt.sh so that it doesn't stomp over the files that ttt.sh makes.

The Makefile clobber rule had a typo fix as well which prevented a file
from being removed (a file specified twice instead).

The README.md file has been typo and format fixed.

The .gitignore file has been updated.
