Try this text instead:

	In C, there is no boolean type but there are boolean
	concepts, contexts that express or test yes/no, good/bad,
	error/success, pointer initialized/not initialized, object
	created/not created, and so on.

	Where a conceptually boolean operand is expected and you
	have a value that is not conceptually boolean, use an
	operator (e.g., ==, !=) that translates the operand to
	something that is conceptually boolean. This applies to
	"if" expressions, the operand of !, function parameters
	that want a conceptually boolean value, and so on.

This is actually a special case of a more general rule, which
might be stated: saving a few keystrokes but violating the
expectations of strangers reading your code is not a good way to
write maintainable code. Ensure that the code and your intention
are congruent *in the mind of your readers*.
