Add try.sh to 1985/sicherman

The Makefile was also modified to have a sicherman.alt rule as it
requires -traditional-cpp. There is an argument that this should be
removed and instead the alt2 version (which is compiled if a compiler
fails to compile sicherman.c because of the 'wrong' number of args to
main() - one arg) would become the alt version because if someone wants
to try the original code they can look at sicherman.orig.c. This can be
done another time if it's worth doing (which I think it might be).
