NestList integration bug?

All: Please comment on the following code:

The following input:  NestList[Integrate[#, {t, a, x }] &, m, 5]         
         (* m is a constant *)

results in {m, m(-a + x), m (-a + x)^2, m (-a + x)^3, m (-a + x)^4, m 
(-a + x)^5}

which is missing the divisors as a result of the integration. However, 
doing the integral indefinitely:

NestList[Integrate[#, x] &, m, 5]  results in

{m, m x, (m x^2)/2, (m x^3)/6, (m x^4)/24, (m x^5)/120}

which is correct. 

What am I missing?
