After getting some help working through my bugs, I have what seems to
be a robust, working word counter script. I post it here to benefit
others that might want this in the future and so that if I ever lose
my copy I can come back here to find it
Some other scripts that I
used for inspiration failed when confronted with whitespace before the
string or miscalculated when encountering linefeeds and other
non-space spaces, so I made mine better. Definition of words for this
exercise is contiguous groups of characters separated by whitespace.
Maybe it will even be useful to somebody besides me.
Cheers!
