Use "XXX != NULL" rather than "XXX" to test for a null pointer; either

I'm missing something or the MSVC++ code analyzer doesn't realize that
in

	if (XXX)
		dereference XXX

will not dereference XXX if it's null - maybe "if (XXX != NULL)" will do
the trick (if so, the code analyzer is buggy, because "if (XXX !=
NULL)", "if (XXX != 0)", and "if (XXX)" mean the exact same thing if XXX
is a pointer-valued expression, really, truly, even if a null pointer
isn't represented as all zero bits or if it's wider than an int).

Clean up indentation.
