Make 1992/westley whereami code scripts

It is not actually necessary to have a program that uses curses to get
the number of columns. One can use tput cols or stty size to get that.
Thus there is no need to have a C program that links in the curses
library.

+# whereami.alt - a wrapper script to westley.alt.c that checks first the columns
+# of the terminal, exiting if < 80 and otherwise try compiling westley.alt.c
+# (with make) and then if is already compiled or ends up being compiled it will
+# be run with the specified args to this program.
+#
+# It is an error to not specify two args but it is not an error to specify args
+# that are not numbers. The atoi(3) function typically returns 0 in that case
+# which westley.alt.c uses.
+#
+# The reason to use this wrapper is because westley.alt.c needs at least 80
+# columns to show the output right. Previously it required 80 column wrapping
+# but in 2023 this limitation was removed, allowing it to work as long as there
+# are at least 80 columns.
