A reasonable recommendation, imho...

look at it like this for once:

basically, the first expression says:
	if dereferenced-pointer-value of p is the nul character, then ...
whereas the second expression says:
	if not dereferenced-pointer-value of p is not integer zero, then ...

maybe you might understand why some people prefer the first expression,
even though the second is "faster to type".

(I personally prefer the order "'\0'==*p", for hopefully obvious reasons)
