makes it easier for a human to read the code.

If it does not make it easier to read the code for you, then maybe you
should consider that this might not be true for all humans. For me, it
makes it much easier to see at a glance, that code like
ptr=malloc(sizeof(*ptr)) is correct.

I don't think there is a perfect solution.

Maybe. But for the second variant the correctness is easier to check,

How often should
	ptr = alloc(sizeof(*ptr))
be
	ptr = alloc(sizeof(**ptr))

 both mentally and programmatically, because there is no need for any context (the type of ptr does not matter).

Context matters.
