Dereferencing NULL pointers

[Henry Spencer]

There is an unfortunate naming clash in C's use of NULL for the zero
pointer, since the ASCII standard specifies that NUL (note one L) is
the name for '\0'.  It would have been better to use a different name
for the zero pointer, perhaps NIL as in Pascal.
