I disagree completely with your statement that this is shoddy. My view
is that
you assumed too much.

Perhaps the language that I put in the example mk.conf could have been
better,
but I do remember taking a lot of time over my choice of words. Most
people who
know me consider me to be a pedant, especially with the English
language.

Almost all computer languages I can think of, and most spoken languages
as
well, have different meanings:

In C, char *ptr = NULL; is VERY different from char *ptr2 = "";

Or take English, for example. Existence of a book is one thing. Whether
that book
contains any written words/ideas/clues is another, completely different
thing.
