Nice example. The source seems to draw a distinction between isblank,
terminology available, I learn, in C99, and the more familiar isspace. The
word "blanks" is used in the documentation, but not as frequently as the source
suggests and not, afaics, in relation to the "words" function. I retract my
previous suggested patch in favor of this. It doesn't go nearly far enough,
but verifying each mention of whitespace now looks like more than I'd bargained
for.
