Change INABIAF status in 1992/westley

It was an error to fix the segfault without enough args in 1992/westley
as it does not in fact affect the usability of the program and that's
the only time a segfault should be fixed except by anyone but the author
themselves.

This commit required also changing the alt code (that I added based on
the author's remarks) as well as the README.md, bugs.md and
thanks-for-fixes.md.
